Honestly, I don't follow predictions of the said sports gambling experts but I do read their analysis about the game. It's really helpful to see who are missing in the game and who might play that could be a big impact to the game.
After that, I do my own analysis and I'd be happy to predict the results of the game on my own rather than relying on someone else who thinks they are good at predicting the game. Reality is, there's no assurance with their own predictions because the game cannot be controlled by anyone unless there are circumstances where they need to lose because of an important reason. i.e. Draft picks lottery (tanking)
Yes, that's true, we cannot trust 100% in the predictions of gambling experts, because the final result of the match/gambling is not determined by them.
When his prediction is correct, it is luck, but if it is wrong, we cannot hold him responsible for anything.
but there are benefits if we listen to their analysis, for any number of reasons so that they can draw conclusions. then we take advantage of that information
We can only use their predictions to add information to the analysis we will make so that it might give us more clues to discover other things. And with that analysis, we can determine which team we will choose so that we will learn to analyze well. It can also improve our analytical skills so that we are not dependent on other people's analysis.
We can get several benefits from other people's analyses to get more information when placing bets. But we can't trust their predictions if we haven't found other information showing their predictions will come true.
