Perhaps faith as opposed to confidence a person is more likely to put something at stake to represent the sentiment?
Like a person sky diving and trusting their god and religious beliefs with protect them. They literally put their life at risk. I suppose thrill is the main reason for sky diving so maybe an example more along the lines of joining the military is better.
Meanwhile confidence that isn't faith is making conclusion about the odds, but without really risking anything to make a point? — TiredThinker
Like @Tom Storm, I'm someone who doesn't usually use the word faith, unless it's a religious context, and even then usually only when a believer brings it up first. Tom Storm said the following:
To use 'faith' to describe plane flight or crossing the road is a rhetorical tool used by apologists who like to equivocate on language to help them smuggle in their ideas. — Tom Storm
I relate to this. There's a bit of a difference with me, since I usually don't have to deal with apologetics. Austria, where I live, is a fairly secular country, so the you-have-faith-too line is something I've only ever encountered on the internet. It's not a thing around here.
But the point is this:
Atheist: I don't believe in God, that's all.
Theist: But you have faith, too. For example, everytime you [insert examples, say the ones from Tom Storm's post].
And, my intuitive response to this is pretty similar to Storm's: that's just not faith. But other than him, I don't see "confidence" as an alternative. I'll have to backtrack a bit at this point:
When I read your opening post, my immediate question was: what is faith to you in the first place? I can't talk about types of faith without having a clear idea of where you draw the line. My own concept of "faith" is fairly narrow: a type of trust in a person (or person-like entity to account for the religious use) backed by some sort of commitment to that person (or person-like entity).
In that sense, I could actually sort of go with the apologetic usage "but you have faith, too," to some degree. It's helpful to understand how they relate to god, in a metaphoric way. When I cross the street I put my faith in the drivers; they will not run me over. When I get on a plane, I put my faith in lots of people: engineers and pilots come to mind. And so on.
Except I don't think that's actually happening. One crucial element of faith, trust-in-a-person and religious version alike, is that the commitment to trust backs me up in a moment of doubt. But the thing is this: if I walk across a street and suddenly a car speeds towards me, I'll do my best to get out of the way. Whatever I supposedly have faith in, it's certainly not that particular driver in that particular moment. If this were a type of faith, I should just be walking across the street as always. I have faith in the traffic system. It cannot fail me. That car will stop. The traffic light's green, after all. Faith, in this sort of situation, would cause me to act like a self-endangering idiot.
If the but-you-have-faith-too rhetoric targets me, I could accept that and use it as basis of definition of what faith means to the believer. So, when I get on a plane or cross a street, do I think I can never be hit by a car, or that planes never crash? Obviously not. That which I put my faith in is fallible; I know it to be fallible; and that faith is predicated on that fallibility. I need to put my faith in say a pilot or car drivers, precisely because I know they could mess up and harm me (or even deliberately harm me, who knows?). This works for person-faith, too: you commit to your relationships; you don't let go of that trust easily. And in turn you attempt to act trustworthy, too.
But abstract enough, apply it to God, and I, an atheist, am left with... nothing that makes sense. What it looks like to me is this: From early on, you put your trust in God the way you put your trust in your parents. And by the time you differentiate between fallible people and the triple-omni God, that faith is in place and it needs a target. The meaning of the concept is quite literally what you put your faith in. Basically, faith constitutes God by way of the trust-people metaphor.
But obviously that's not going work very well as common ground between me and a believer. So now we can have alternative concepts that - to some degree - does serve as common ground; at the very least we'll know where we part ways if we can figure this out. "Confidence" though doesn't do the trick for me, mostly because I think it's a red herring.
What I think happens when we cross a street or board a plane is that we have implicit working assumptions which are based less on confidence than on habit. We just don't think about what can go wrong until there are signs that things might go wrong. I think that's just basic human behaviour. How we react to having these habitual working assumptions challenged depends on the person. Me, personally? "Shit happens" is more likely to calm me down than "everything's going to be all right," for example. Other people might find that putting faith in the pilot might calm them down. Either way, the plane's either going to crash or not.
This where we segue into you example: Sky diving. A repeat quote, more selective this time:
Like a person sky diving and trusting their god and religious beliefs with protect them. They literally put their life at risk.

They both literally risk their lives. Risk isn't the difference.
In my experience, putting faith in God usually doesn't mean that theists feel safer. The Christians I know, were they praying for a save landing, wouldn't few the prayer as some sort of petition. They take the risk, and they take the responsibility. It's not about being safe; it's about re-affirming the relationship. If things go wrong, maybe God will save them, or maybe He won't. He'll know best. Sky divers don't want to die. Sky divers likely won't die. Most of them don't. But should the worst happen? Well, they can only hope they lived the best life they could, and there's always heaven (actually, the details are up in the air). People who put their faith in God affirm a relationship, not some sort of confidence in an unknown outcome (like surviving sky diving unhurt). Christian sky divers might risk their life, but their faith protects them from risking their relationship with God, should things go south.
Atheist sky divers certainly risk their life in the same way. And should they put faith in their own abilities, they might risk their pride (and that faith could lead them to blame, say, manufactures of equipment and prevent them from seeing their own short comings; which won't matter much if they die, but could be disastrous if they survive with wounds and go on to make the same mistakes again). But they can't (from their own perspective) risk their relationship with God; they don't have one.
So up until now I've treated faith as trust in a person or person-like entity; but you can actually direct a similar energy towards your habits (like, say, rational thought). It's served you well until now. It's, I think, a variant of putting faith in yourself: when I do this I succeed, and if I don't it's not my problem. (I'm a rational atheist; those are irrational theists... and such.) Come to think of it, this is where "confidence" comes in after all. I have no trouble of thinking of that as some kind of "faith". The difference seems to me mostly... rhetorical?
I think what faith and confidence have in common is that they can help you stay calm when your habits show signs of failing you. Faith is the ultimate skill in that respect; I suck at it. I don't mind much, though, since faith tends to lower you perception skills when in use. I do mind some, since anxiety - what happens to me when my habits are failing me - also lowers my perception skills. The trouble with the faith skill is that it activates when not needed, too.
Maybe I could express the difference between confidence and faith like this (I couldn't tell what the sentence means, though):
It's quite easy to be overconfident, but you'll never have enough faith.
