In the moment a gambler can beat the casino but it is more likely to happen by chance than because of the actions or experience of the gambler. It is such winnings make us again and again to try our luck at gambling. Even if after such a win you lose all the money you still have hope of winning. At such a moment it is very important not to give in to emotions and withdraw all the money from the gambling platform. In the long run, of course, the gambler will lose more than win because gambling is a zero-sum game.
It is probably possible to beat the casino if you are lucky enough to win the jackpot from the very beginning. But if a player plays for a long time, many years with big losses, but continues to play because he believes that he can win, then even after winning the jackpot, his positive balance may not be that big, given all his previous losses. But I understand that many players play with the hope of winning the jackpot someday.
It takes a very good luck to beat the casino and even then it is very rare, in the context of how to beat the casino actually no matter how smart and clever you are you still won't be able to beat the casino as long as you keep playing in it, because as long as you play you will still be faced with risks. So in simple terms in my opinion the only way to beat the casino is when you manage to get a number of wins and after that you stop completely from the activity and then secure it and also enjoy the money from the winnings, believe that greed will only bring you a lot of losses and regrets.
