It's not that easy buddy and a gambler will continue to gamble even if only within their limits because when there is an attempt to actually stop completely there will be anxiety and a desire to come back again.
Even though there are some who have managed to stop and stay away from gambling, they have done many things and it is not as easy as we imagine.

A gambling addict who is absolutely crazy he doesn't care whether he goes bankrupt or loses all his money because he can still borrow from others to continue his struggle.
Even worse, there are also those who are willing to commit criminal acts to make some money as gambling capital.
