I am someone who has always had the understanding that no one can live as a gambler, regardless of whether he is rich or not. Gambling cannot be used as a source of income, you can imagine how a person can live by gambling while he has to spend every day to live while he does not ensure that every time he gambles he gets money, psychologically this is something that can be accepted.
You've got a point .. basically, when someone is gambling they are taking risks for uncertain results in the hope of making a profit. So making gambling a source of livelihood is something that doesn't make sense because they have to depend on something uncertain.
But strangely there are people who take this path which in the end they will be faced with losses and after all the house always has an advantage because the odds are created to the house's benefit.
There are actually alot of people who live off on taking risk. The important thing is to minimize risk as much as possible.
The problem with gambling (taking big risk) is that you'll most likely not make consistent income/profit doing it.
However, people can earn consistent income from betting (not gambling) if they are skilful/experienced in games/competitions they bet on.
It's hard to reconcile the words Betting and Gambling and apply them on topic like this to mean thesame thing. One involves alot of risk while the other could involve little/no/big risk. Betting is the general term.
So, you could lessen your betting risk and be consistently profitable. It will be really hard to take hugh risk and be consistently profitable... bad things could ruin your betting career if you take big risk regularly
