I have no doubts there are indeed some gamblers out there which can indeed make a living out of gambling, but how many of those that try actually reach their goal?
It all depends on the gambler involved in this kind of situation, making gambling as a source of income isn't bad at all as long as the gambler can always sought a means out for himself everytime, he has to be engage in doing multiple things at a time to enable him have two or more means through which he generate income from in gambling, such could be in placing bet, running a campaign for a gambling platform, one can also be their developer or apply as a casino operators and many more and get paid than relying only on betting to meet up to standard of living.
While the lifestyle may seem attractive to some, very few have what is needed to achieve this goal, and this is because most people are used to work a 9 to 5 kind of job in which they know in advance how much money they are going to be paid, but a professional gambler has no idea at all of how much and when they will earn any money, adding a great deal of uncertainty to their lives.
It's not every gambler that can have interest in this kind of situation, gambling is not a fix or guaranteed means of earning money, one can rather be loosing more than earnings from it if he so depends on the bets he made, but as being said earlier, additional means through gambling will make things work out more, one can get money which other job couldn't offer.
