Only some gamblers can use gambling as a regular job, while the rest will fail in the middle of their journey. It is hard to use betting as a job because that needs more knowledge than regular people who bet. If you can get paid by playing poker tournaments, then you do not risk anything since you only need to use your skills, no matter what the result is in the end. But everything related to gambling will have a risk. Whether that risk is big or small, you will still get that risk. The only thing that makes it different is how good you can manage the risk.
