I do not know if there are players who managed to beat the casino in the end, even temporary successes do not guarantee anything, probably you need to be a genius for this to be possible.
i guess if someone only plays once and ends up winning more than what he paid for to play
like if someone were to buy a lottery ticket for the first time and wins millions and never goes back to gambling again but the chances of that are low and chances of getting rich and not going back to gamble is also lower
