For me gambling could be a profession for sure for a lot of people but it was really risky for a lot of people maybe if you have a lot of money or already have a lot of businesses and passive incomes like apartment or restaurant, you already have a source of income that you could use in gambling and have a chance to win as your profession. But surely if your already a professional in gambling you should not reach the point where already gambling all of your money you should always limit your money to gamble.
The risk is not worth for every people because they need to spend time to learn the skills in gambling. They need to have money to learn the lesson, and they must prepare for the lose that always comes to them at any time. Although you already get passive income, it doesn't guarantee you to have a chance to win in gambling because you know that gambling will be related to luck. It will be difficult to be a professional in gambling because that will need time and learning in gambling, and not all people can do that.
The first money that I deposited in online gambling site is the money that I can afford to lose which means it is the excess money from my savings. I accepted the risks that I am taking and I know that my money is not safe in there because in gambling there is no assurance of meaning and there is only possibilities. Many people got depressed in gambling because they lose big amount of money in there and they didn't identify the risks that they taking. Their allocation of their funds are also the problem.
