Gambling is unpredictable. Thus, there is no single betting strategy that will lead to regular wins.
You can't generalize like that as there absolutely are people who make a living through sports betting. Maybe not OP (since they haven't shown proof), but legitimate professionals exist. These bettors consistently make quality picks and have proven long-term profitability. Just because most people lose doesn’t mean skilled, disciplined bettors can't win over time.
Have you come across such professionals personally, I think it's time to stop believing what people tell you online. He has a point, there's absolutely no way to get regular wins I'm betting and there's no one that makes a living through this means except they are just lying. Professionals make Their money from others when they predict games and other bettors copy their bet and also use their link, such people would always say that they play sports betting for a living but that's just to get your attention.
