It is possible of course, but then how stable does gambling it could be? Many people wants to settle their family with gambling, but end up to become broke. In my own opinion, it couldn't be we all know that you will experience losses in gsmling as well, soemtimes you will not get anything in return, all you have is the debt because you spend too much and you don't have anything now. Gambling can't be taken as passive income I'm sorry, I still treat it as recreational activty.
