You don't get to be specifics here dude. All gamblers really know the consequences of being addicted to gambling. But why they are still getting into it despite the negative effects of it? Simply because they want to enjoy and earn lots of money in the quickest time possible. And no amount of explanation will swayed their mentality.
Yes all gamblers know the consequences if they continue to gamble even to addiction, but there are so many gamblers who do not seem to care about the consequences. They think that gambling can give fun and quick income.
