Making gambling a part-time job is already risky. How can you think of making gambling a full time job and talk about a career in gambling? Gambling is a business but that is only for bookie and casino owners. Players are people who are willing to spend money on betting. So players cannot make gambling a job because from the start gambling is just a game and you can get addicted to it and harm you and your family. I think I need to provide an illustration that can make you think again about your idea.
