Most people would think that winning the casino would mean winning the jackpot. But this should be followed by withdrawal of the said amount and not gambling that away.
For those who keep on gambling away their wins the casino is winning and not the player.
I still believe that thae actual winning from a casino is if one manages to stop playing completely.
For me, it is not necessary to hit the jackpot to beat the casino. You just need to stay profitable, to win more than you lose. Even if the amounts are small, especially if you play not for income but for entertainment, and still manage to keep a positive balance from gambling, I think that is already a win for the player. I have never set a goal to beat the casino, because I understand how difficult and, in many cases, pointless it is.
