Of course it is very easy if gamblers can stop their gambling habit if they continue to accept defeats in gambling. But for people who are addicted to gambling, it will be difficult to stop... because it has become their habit. every week or even monthly to improve his family's economy.. it's impossible for him to stop..
True, when it comes to addiction it can be extremely difficult to overcome as it requires strong dedication from the gambler as well as time. However, for a casual gambler who does not have a severe addiction quitting can be a matter of personal choice. They may decide to quit when they face losing streaks or when they encounter financial or family problems, and so on.
Long story short, if a gambler still maintains control over their gambling habits there is a big chance that they can distancing from it, but if they lose control over themselves it becomes significantly harder to do so imo.
