Vegas really is very well regulated. There are some extremely ugly sides to gambling, but if you're going to have it, vegas is a pretty good starting point for how to try and keep things under control.
There's no casino in town that will "look the other way" for a few 20 year olds who want to gamble, because doing it once could lose that operation it's gaming license.
There's no casino that's going to on purpose risk going above the 25% max hold, because again, you could lose the ENTIRE OPERATION.
The rules are rock solid (sorta....simplifying) and heavily enforced, and while at the end of the day all the machines give worse odds than the ATM, there's caps on what you can and can't do.
Somewhat ironically, I'm not sure if it's changed, but if a slot machine shows you a "pick 1 of 3" choice, it's never a real choice. The decision was made before you picked. Every "pull" of the lever determines your payout basically instantly, ALL the shenanigans after that (including free auto play games i believe) are just placebo/different ways of doing a jackpot.
