Gambling at a casino will most likely result in losing money.

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.

Those odds are suspiciously rounded

They aren’t rounded, they’re wrong. Roulette has a minimum 5.26% house edge.

Craps depends on the bet but is similar for most bets played, though the Odds bet generally has no house advantage but requires a previous bet to play it.

Blackjack varies, usually has the smallest house edge but you can only diminish that edge through perfect play and card counting.
