I guess it's safe to say that the most vulnerable to gambling addiction are those people who doesn't want to work hard to get rich. These kind of people wants to get rich faster without getting into a lot of works and sacrifices, as they typically just want to gamble primarily and solely for easy money. A person who gambles for fun, doesn't really matter if he wins or he losses, because losing is part of the system and winning is just an extra reward while having fun. The people who gamble for money will always end up chasing their losses and always wishing for a jackpot.
