Some of those gamblers addicted on gambling so that they dont care if they will loose their money.They cannot learn from their mistakes instead they would still gamble and get addicted on it they cannot control their selfs from playing.
They are already addicted, what more can we say to them?
Actually there are gamblers who are responsible enough, they do not gamble if they don't have money or if they do, they are setting a limit so they won't reach the point where they have to pull everything in their closet for them to atleast have money to bet.
Those gamblers who never learn are gamblers who bet with almost everything I think are fools. They always have the thought " for the sake of gambling", "This is my passion". Not thinking that they are not doing well in it.
