If we start treating sports betting as a career, that’s a whole different conversation. It means we’re fully confident in our ability to turn a profit, but sometimes, what we expect just doesn’t happen. There’s a lot of groundwork needed before taking it seriously.
The first step is proving we’re actually good at it, and that requires proper documentation. By that, I mean a detailed betting spreadsheet with at least 1,000 recorded bets. If we can maintain a winning percentage of at least 53% (rounded off), then we’d have a real reason to convince ourselves that pursuing this as a career is worth considering.
I'm skeptical about the real possibility of making sports betting a career for the average Joe. Even if he was skilled enough to get a consistent 3% profit, I would consider it not worthy the risk (a bank deposit already gives you that return with almost no risk). And, on the other hand, to get a great benefit, you'd need a lot of capital most of us don't have unless we went into debt.
In coherence with my last post above, I'd prefer to make improbable bets for the sake of fun (and, if lucky, get a good prize) than making a lot of little "sure" bets and turn it into a job, as not even the greatest sports experts are usually known for having become billionaires betting thanks to their insight, and I don't aim to know more than them.
