Every gambler or individual has to decide how they want to perceive gambling. Whoever sees gambling as a means of making money, once they try it out and it becomes profitable for them, then it is their decision to continue gambling and earning from it. But if they venture into it and discover it is not a safe heaven of income-making, then they still have the choice to stop or continue. But the honest truth is what you have said, and several topics here have also been preached about. Gambling is not a means of earning a sustainable income. If anyone really takes gambling very seriously as a means of income, sure, they will only become compulsive gamblers and will not even become rich.
