Gambling is an industry for owners and for customers gambling is a game now it depends on which side you look at it from
What you said above all right can be called a career can also be called a troublemaker all possibilities can happen
But in general, gambling is not part of a career because it causes more problems than profits this reason can be admitted because almost all casinos make a profit.
It can entertain the gambler, make him have a nice time, satisfy his ego, but I don't think it will make him rich. When he earns some money, he will demand more. This will prepare the end for him. If he is married, there will be troubles in his nest. Playing big hurts everyone. The winner is always the table.
