I'm not sure it's effective - the risks are too high. Even if there are some people who really make a lot of money from gambling - that should not be your basic motivation for making gambling a source of income. I'm sure there are only a few successful gamblers and they are famous influencers - the rest are losers with big ambitions. Gambling is just a place to have fun - this business is not for those who hope to get a steady return worthy of being called a source of income.
