This can only be possible if the person happens to have other business being established that are giving them enough money to take finance the family, there are other people who solely depends on gambling to feeds and earn a living, and there are people who took it as full time jobs their function is to constantly predicts games and sales to people who wants to gamble. This types of people do not regularly gamble but maybe with how often their games are played if the sold to people who keeps playing their games then they will decides to gamble in few of their prediction but that doesn't mean their spouse would entirely stops them from what is putting food in their table.

Let me draw our attention and renew our mindset concerning gambling, naturally gambling is not a bad thing what makes gambling looks very bad is when you starts going against the gambling ethics, like becoming an addicts in a way you can no long control yourself toward it or people who don't play's it responsible are the people giving out this impression that gambling is bad. For instance, when you are hungry you go get yourself food to eat and after eaten to your satisfaction you don't keep eating otherwise it would cause another sickness to yourself because of excessive feeding which would either leads you to constantly vomiting that need a cur for it, so is everything in life.
