Gambling cannot be a career. Gambling is played for fun and entertainment. To relieve one's stress. It's not something to be made as a source of income. You can earn a lot by gambling, but that doesn't mean it's a job. Come on, man! Gambling means betting on something of your life. How can one bet on their life? They have to feed their family, don't they? If I were to make gambling my only source of income, then I would be the foolishest person in this world.
