If we are talking about pure luck, people can get lucky anyway possible, you can hit by a million dollars hit you in the head dropping from somewhere when you are walking to a shop, you do not see people walking around hoping that would happen. I can tell you that the possibility that you could maybe get richer is just something that is designed to make you believe that it is possible so that you would lose even more money. Casinos are getting richer and richer, how? They are getting richer by the fact that they are taking all our money, sure they make a few people win here and there to convince you that it is possible, but who says you won't be one of the millions that loses, and be the few that won?
