Genshin shows odds, Valve shows nothing.

Genshin directly shows you the stuff, Valve has a slot machine like animation.

I have students who play both Genshin and CS2 and spending money them. In Genshin they spend to get a character they want, in cs2 is to try to make money…

And casinos can hardly be honest given the couple of time I read about cases in which a customer wins at slot machine and casino claims it was faulty.
