yes it is possible but only if you approach sport betting as a long term investment and plan. There is value betting and arbitrage betting which bring guaranteed profits over time. But it needs a significant bankroll to make a full income out of it. If you know with arbitrage betting you mostly make 20-25% profits on your bankroll monthly. So it needs 10k to generate about 2000-2500€ monthly.

One thing I know for sure is that if you rely on the betting part of sport betting than mostly you will not succeed. Bookmakers always have an edge over punters. So you will need to have tools and strategies to turn that edge in your favour. And that is exactly what you do with arb and value betting ..... and with trading the sport markets.

But in any case you need a significant amount before you can start mak¡ng a decent income out of it. If you rely on hitting a 50+ odds accumulator every single week than you will never make it
