it's up to the person if he wants to get rid of the gambling habit, it's easy for him but if the person loves gambling, it will be difficult for him to quit My answer to this question is that it depends on the person
When a person is deeply addicted to gambling, it is very difficult to stop the person from gambling. Although a winning addict hopes to get rid of gambling, if he does not gamble for a few days, his addiction is drawn back to gambling. In that case, if a person cannot control himself from gambling by his own will, then it is very difficult to bring him back from gambling. But if a person who is not addicted to gambling loses a few bets, he will surely come back from gambling. It is true that a person's gambling habit will depend a lot on his gambling.
Though I don't completely grasp the point you tried to pass in your comment , let me just say that indeed, quitting gambling after one is already addicted to it isn't easy, but then , how difficult it is solely depends on how deep the gamblers addiction is, addiction are of different levels, there are gambler who are addicted to gambling but can easily and effortlessly quit gambling if they find a good reason , while there are other who are already too deep into the addiction that quitting requires not only their own effort , but also the effort of relatives , friends, or even medical practitioners ..
And honestly speaking now , addiction to gambling has little to nothing to do with win and losses , win and losses only matter when a gambler is not addicted to gambling yet, like for example, some one who's not addicted to gambling can easily quit gambling after gambling for a while and won nothing, but for some one who is addicted , he or she will just keep gambling no matter how much he or she is losing .
