It is not wrong in my opinion,
It's just that you loose money when you gamble, so its not good for you in the long run.
I'm not sure about that. Anybody, he lives to gamble and makes his living gambling
So. I think he can get a profit in the longterm.
You say anybody, I do not think so. Gambling for living is only suitable for very professional gamblers. For most people, if they are lucky, they can win some time, but lose in most times. This is in the design of each games. The house has an edge. If there is no hose edge, there will be no casinos.
