The bitter truth is that gambling casino are rewarding to themselves only and I don't think there is any casino which is happy to give his customers money.
Even though casino give you bonuses and promotions and the gamblers think that they are being rewarded but in fact all of this money is taken back by the casino when the player loses in the gambling.
Yeah. Of course, it is almost impossible to find such a "happy" casino that will generously endow players with money. All such casinos would immediately go bankrupt and disappear, even if one theoretically assumes their existence. The only question is how generous this or that casino is and allocates a larger percentage of all players' bets for winnings. Or in other words, a casino with minimal operating costs. But it is difficult to find such a casino because there is no reliable information.
So the question that the OP posed to us here will not be definitively solved. But it's worth discussing.
Casinos are created with the sole purpose , and that is to make the owner rich and famous and there are so much expectation from each casino when they started to open each casino.
but of course there are chances that players or gambler won over casino houses but this is at least 1 out of 10 to happen so yeah casino will not let us gain while they are losing.
