Well it can be very profitable if you made a lot of profit from it. If you make like a million form gambling it will be profitable on a long term.
I wish gambling was profitable over the long run but it ain't.
But you shouldn't make gambling main source of income. Because gambling is not stable enough to do that.
Yeah, gambling shouldn't be anyone's main source of income. you only win in gambling whenever you're lucky, someday you win someday you might not!
