Yes, you can beat the casino. You just need to win big, and your winnings will surely exceed your entire lifetime investment. However, only a few achieve this.
But it's a very different thing for you to win a significant sum of money, and another to make the casino lose money. What generally happens in these cases is that you win the money others have lost, not the casino's.
Absolutely. You won what others have lost, so you don’t still win over the casino, because casinos will always have its house edge over us. And in the event that we are in the streak of winning, most likely the other players are actually in the losing streak, so they are losing the funds that we are supposed to win.
Betting in a casino is a business, so there’s no reason that they will give free money for us, or they will let us win over them and left them with huge losses that may lead to their bankruptcy.
