This type of data highlights a better understanding of the opponent's strength and weakness. I think there are more details to consider, of course, and they vary to each player's strategy
However, I wonder if the personal/professional lives and details (of soccer players), such as lawsuits, scandals, fights between teammates, absences from training, etc. can also be a source of data to make a more informed prediction? If yes, how can I collect this news daily?
The answer to this question is yes, you can make a well detailed and informed prediction with statistical betting but you can't always get an accurate result. Some people that are into sports betting don't really take out time to understand and get acquainted with the betting system, they prefer to just get their predictions from paid sites which isn't always a bad idea, but how sure are you that those experts are analysing those games properly? It's would be of more benefit to you as a gambler if you can analyze your games so you won't end up having a double loss.
