I am not, and if it was just a situation where I have to make a living out of this, I would not be picking sports betting as my go to situation. I mean it's such a risky thing, I would rather do like trading or something to make it and I am not making my living out of trading neither, that's also quite risky but I would pick that over gambling at least, because there is no house edge or anything like that.
The whole point of gambling is to make sure casino wins, they are a business and they are giving you chance to win money by making sure they have a higher chance of making money which means that you wouldn't win on the long run and that's why I wouldn't pick it at all.
Its a risky thing and no one could easily pull it off but just like others been saying that there are really that people who are really that able to make some income or make money out of sports betting.
They might not be some member of this forum but no one really knows until if there's someone who do make out such claims and would really be that saying that he has done it for it to make it as a living.
4 or 5 digits then it could be that possible but its not something that would really be simple knowing that gambling does impose that huge risk where you cant really that imagine
that making constant profits is nearly that impossible basing off with the risk involved.
