In my opinion, there is no good and consistent strategy or analysis in sports betting, because everything is a factor of luck and analysis can only improve the quality of our knowledge in sports and bring little chance of winning. However, that doesn't mean that every analysis you get will always win.
When you believe that everything is all about luck, then there's no reason to analyze the game as what we work hard would still be useless.
Perhaps try to change your perspective in sports betting as it's not the same as the games with a house edge, here there's a real chance that we will succeed as a sports bettor, and although some may so negative about the word "succeed" in sports betting, if you believe on it, nothing will stop you.
I'm sure you've search search some strategies that could help you win, there are lots of videos in youtube, and even you can find some testimonies from people who claim they are making money in sports betting, so if those interest you, you wouldn't say that sports betting is just all about luck.
