Financially successful gamblers have different spending habits. Some gamblers, yes, were able to set up nice businesses with their gambling wins. But, a huge number of players who think gambling as a source of income is the best, end up wasting their funds. If a gambler utilizes his wins properly, he wouldn't be tagged under players who focus on gambling as a means of making money. Such people rarely produce successful gamblers, monetarily. Although, even if the player is not jobless he'd still wager each day, to stay consistent on his goals. I don't feel it's completely right to tag such gamblers as jobless.
I also think successful gamblers are good at managing their own money. Some gambles use their winnings to start businesses and settle their lives while others waste their money in a wrong way. It is really important to remember that gambling should not be our main source to making money. People who always rely on gambling mostly they have money problems. But gamblers who are responsible and careful with their winnings so we should not assume them as irresponsible gambers because they already know how they should use money in right way. It is good to consistent and work towards our goals even if gambling is just something you enjoy or do it as side business or for mind relaxing. Let's not make assumptions and instead teach people how to manage their money and gamble responsibly.
