I run 4 games currently throughout the week comprising of 12 separate players, some of which appear in 2 or more of the games. Over 30 years of gaming i have GM'd too and played with over 200 players and i still hold that none of them ever asked me or tried to query what the chances of success were on a roll. I put this down to play style, which in my case is all about the story and roleplaying not number crunching. I still enforce the rules, and use them mostly as written but they don't halt the game. Yes my players know roughly how good they are within the system we are using as i explain roughly how the task/skill systems work when they do their characters. And i have still not heard any of them say whats the chance of picking this lock, i have heard who has lock picking and then someone steps forward and does it, or at least tries. I have heard someone say i only have Fighter-0 but give me a gun and i will give you covering fire, that was last Saturday when the ship got boarded by pirates.
I have even discussed this with my players to see if knowing the probabilities would make any difference, and they said not, as long as they know what the scale of skills and attributes are within the system they could get on with the game. Now to be fair, i do have a couple of players who at character generation love to Min/Max their characters so they can be the best at whatever role they have taken, but even they said knowing the odds made no difference to them during the game, they knew what they could do and that was that.
So in conclusion i haven't had a limited experience but i suspect we have a completely different play style.
Based upon your description, either you or they are not being forthright. If they're min-maxing they're aware of the odds and playing them.
Have they ever asked for the difficulties? If so, then, yes, they've been asking about the odds.
It's a case of terminology difference, not playstyle.
