It was easy to say if we are not in that situation and that is what OP is trying to say.
Well, that is obviously wrong because if that is right, no people got into addiction. Unfortunately, it really exists and that is the reality when it comes to gambling - many people lose control of themselves and got fall into addiction.  And you are right, many families got broken due to such issues and sometimes committed crimes. But still, we can stop gambling if we really wanted and committed to doing it, yet it will take time to heal and to finally forget gambling.
