Do you know anyone who is taking gambling as a profession and yet making an household income for living ? I don't think anyone can make consistent income with gambling.
Gambling may give you a lot of money at once or you may lose all your money but getting regular income from gambling is impossible.
Those gamblers that have already a good status can do this. Those fairy tale stories of rags to riches through gambling are very rare but there are stories like that which are unbelievable.
I reckon that getting a daily profit through gambling is hard, it's not that impossible but it is inconsistent if someone does that. It can be a good day today and tomorrow up to a week but the next time, you know what's coming.
There are bad days to anyone even pro gamblers knows about that.
The difference between gamblers and pro gamblers is how they percept things around gambling activities, ordinary gamblers keeps pushing forward and try hitting their luck in anyhow, up to busting all their bankroll, while pro gamblers knows how to stop and quit for the day once they've already met their budget losing inside the house, they knew that there's always tomorrow just needed to plan more deeper to recover what they've loss.
Yes, you are right. The pro gamblers know how to manage their money and have many experiences that will help them to gamble. I think they will know if the situation is not good for them to continue to gamble, and they will stop gambling as fast as they can. The gamblers are still trying to make another winning because they seek their luck in the next rounds without thinking that luck will not stay for a long time.
