Probably yes, as I gamble mainly for fun, so being rich wouldn't affect me that much. I might do it less though, as there isn't that much of a point gambling while rich. Also, if I was rich, I would probably want to hold onto my money.
It's a matter of, do you like being rich? And do you like to keep on being rich? If the answer is both yes, then avoid gambling at all times. Gambling can give you money SOMETIMES, but most of the time it takes them away. So better stay away from it, rich or not.
