More than 50% of the world population gamble in one sport or the other and some are making good money while some are still hoping and praying for their luck to shine.
You can make it a source of income if you want but this is not for me, because I have learn to accept that gambling can't become my source of income, I can often make money through gambling, maybe once in a month or more but it's not a reliable way to make money, if you are looking for more than money making then you can get fun in return. I am not trying to scare you but it's a bad idea if you plan to make gambling your source of income, there is no way to know if you will be one of the lucky ones or the other but it's certain that losses will happen.
