I can't prove whether they're rigged or not; only a serious investigation by the appropriate authorities can tell. But we know the house always has the edge. Casinos don't profit from how much you bet, they profit from how much you lose. Therefore, I can say that their greatest interest is for you to lose. But first, they'll let you have that taste of victory, because that way, with confidence, you'll bet more money.
This happens to almost every gambler, in the first stage they win a little, and then they find a kind of confidence in themselves, then the gambler feels that they are winning like this, and then they cannot stop gambling. They start gambling completely addicted to gambling, and then their losing streak starts, but then despite losing continuously, they cannot stop gambling immediately. They cannot stop gambling before losing all the cash they have in their hands. It is like a cycle, and once you are immersed in this cycle, you will definitely face big losses.
