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.
But you shouldn't make gambling main source of income. Because gambling is not stable enough to do that.
yeah right if you can be lucky from time to time maybe its profitable for you but its once in a million that you can always win and never faced defeat
so better to keep gambling as part of entertaining and nothing else don't go beyond that because there's always a negative impact to your life.
