Exactly when someone can have betting limits in gambling is a real winner because basically no one can beat a dealer.
Even though we can win a game or bet, in the future we will definitely lose and the loss can be more than what we got before.
But unfortunately not all gamblers can exercise self-control to maintain their finances when gambling.
Yes theres no one can beat the dealer if you are talking about making the casino bankrupt but a user can manage to beat them on a single session. Beating them by means of having a profit at the end of the game.
You are talking too generalized. The only way that you will surely lose in the future is if you are betting continuously since house edge will surely consumed part of your bankroll. But if you are talking about a sure defeat in the future despite user is just occasionally betting then its wrong because the game is still a game of chances and not predetermined.
