Your point is correct. But unfortunately, not all gamblers strictly adhere to such rules. The fact is that many of them start gambling sober, but when they lose, they lose control of themselves.
After that, such problem gamblers drink alcohol in the hope that they will feel better about the loss. And what's funny is that after that they go to the casino again, and lose even more.
These are those gamblers who have addiction I don't wanna mean that all gambler who did this are addicted gamblers but these happened are seen by mostly on the addicted gambler who took gambling as not as the entertainment purpose they making it a earning source where they can make money and in this time they lose their control when they face losses and chase the losses to make profit or they make more wager to win more bigger amount.
I think these activities are controlled by the gambler if they took gambling as an entertainment purpose and do the responsible gambling.
