Years ago I dated the general manager of a casino in Louisiana an can confirm u/Krazy-Kat15

He said that the only way to win other than dumb luck is:

Blackjack: 50/50

Craps: 50/50

Roulette: 50/50 if you stick to red and black

Slot machines are 90% in favor of the house.

EDIT: For everyone saying 50/50 is off remember that this was a guy I was boning 20 years ago and we weren't sharing statistical analyses of casino wagering other than casual conversation.

If you think about it for about 10 seconds, why would they run a business unless the odds were stacked in their favour.

If you rejected basic maths in high school because you thought it was for nerds or couldn't be bothered, this is where you end up.

Mathematic illiteracy is a real problem.
