If those who have money will consider gambling as a hobby, I think they will regret it especially if they often lose from gambling. Gambling is not a hobby that can be done by people because there is a loss factor that can make them lose everything in the end. Maybe if later there was a thesis issued by an educational institution about how dangerous gambling is to people, it would help them to think twice if they wanted to gamble.
Whenever you write a thesis, it's usually in the favor of the subject matter. It's not common to write thesis telling the disadvantages and drawbacks of gambling.
Anyways, is there any thesis on luck? Since gambling is only luck based, i don't think a thesis may help you win in gambling. And also, gambling is for those who have money to lose, so if you do not have extra money, stay away from gambling.
