Firstly I don't think there is any logic in winning sport betting, although before placing a bet you have to consider and analyze a lot of data, but it still does not guarantee you winning. But my advice to you is to bet on the simple things like goals and still it is not still guaranteed . So you should realize that there is no known method in winning, I think it's just lucky.
Why doesn't logic make sense in sports betting? What kind of analysis would you conduct? I personally don't sweat about it too much; I see previous matches, the teams' performances, and the odds, while also taking into account who's more likely to win based on logical observations. Does it always work? Certainly not. Sometimes sports betting doesn't "have" to be logical or statistically proven, and eventually you'll even see the team you least expected to win secure the match.
