Apart from that.. I think people gamble or not, depending on whether or not they are close to gambling, the more addicted they are.. the more determined they will be to gamble without thinking about it that actually we should be responsible gambler.
In general, indeed basically we have to be able to manage finances, make gambling as a free time filler without having to have an excessive sense of interest.
I firmly believe that if you are gambling then you aren't able to manage your finances because gambling is a waste of money and people who gamble knows that subconsciously but they are there for the entertainment and the wins are just a part of the game. The problem is that sometimes the obssession can be really strong that it's difficult to control it especially if you are being afflicted by the behavior of gambler's fallacy where you think that consecutive losses is going to give you a big win anytime soon.
