Quitting gambling is a difficult task for a person who is addicted to gambling and who gambles regularly. You cannot easily get rid of something that has become a habit. A gambler loses a bet and when he later gambles again to recover his losses he loses again and at one point he gets bored and plans to quit gambling. But after two or one days the person is again involved in gambling and as the reason he mentions that he was wrong in the amount of money he lost and he will not make that mistake now and he will recover the money he lost. A gambler will give you a thousand reasons why he gambles because he somehow doesn't want to quit gambling so he has multiple reasons to gamble.
When someone is addicted to gambling, of course they will find it difficult to stop gambling, because with them being addicted to gambling, their thoughts will only think about winning, and that will certainly encourage them to continue gambling even though they always lose. With them gambling and ending up losing and then returning to betting of course it is not a good solution, but if they can stop when they lose and return to gambling the next day it might not be a big problem, because what should not be done is when they lose in gambling and return to betting on the same day after experiencing that defeat.
Of course they must have their own reasons when other people ask them why they continue to gamble, but I don't think they will admit that they are addicted to gambling, it's very unlikely because I think they will be embarrassed if they admit that they are addicted to gambling.
