They claim that it is fun because they can do nothing to control their addiction but to give in to it. They know for a fact that they are wasting their time and money but that gambler fallacy still runs wild in their minds. These people are mostly the ones who dont have a steady income because that is what makes people try their luck and gamble their earnings. Those who have a settled lifestyle prefer to stay away from it.
But there are genuine people who gamble once a while in a friendly match and do it for fun - these people are not like the daily addicts though.
It is a good assessment but the facts are far from the situation, you can see many prominent business personalities going bankrupt simply because of their gambling addiction, people who are broke does gamble thinking that they could recover everything in a split second which is the dumbest thought process to being with, i do gamble once in a while and not at all an addict nor i am doing it to make money.
