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.
The victory over the casino is based on the casino losing because of losses and us winning because of profits and seeing the current conditions in the end it is almost impossible to do that because the form and purpose have been very different from the beginning where we only see gambling as a form of testing the luck we have and they are the croupiers see gambling as a form of business for profit so in the end this difference clearly makes us have to be aware of our position and the croupiers in the casino.
The reason some people say they win over casinos is only based on those who do win large amounts of bets but in the end this condition is false where we realize that they only win from other gamblers who lose not from casinos so in the end winning against casinos is just nonsense because it is difficult and even tends to be impossible to do.
