It's true that almost 90% of gamblers are heavy addicts and lazy, but behind that there are people who gamble just looking for fun meaning having fun in gambling without aiming to win or multiplying money, the more the desire to win, the farther we will be playing so that they fall into curiosity and become addicts, addicts always expect that gambling can be their source of income. even though it can never be a steady source of income.
But to be honest, I believe that number is more than 10% because I know that there is a very large quantity of gamblers who are responsible and they take care of everything else and continue their gambling activities when they are free or have extra money.
