Any one who thinks he might become rich out of gambling is a fool. As you said, gambling is an entertainment activity. You spend money to have fun. There is a slight chance to make a win and at a rare occasions to make a huge win, but this is part of the "entertainment" aspect. It doesn't mean that if you bet more you will win more. It's totally the opposite, the more you play, the more you lose. All gamblers should be aware of this.
