I have to disagree with you guys! I don't think it's the lack of awareness about the risks of gambling or how casinos work which make people continue gambling although they lose too much. Am sure most if not all gamblers are aware that they will lose on the long run and know of many cases where gambling ruined people's life's.
In my opinion, it's greed which make every gambler think he will be the exception and hit the jackpot although he knows the odds are against him.
