Analysis is possible, but an accurate prediction that will give you a winning outcome always? Not in any chance, as even a heavy underdog can upset the favorites. You can use this analysis and try to follow up on how those experienced gamblers take their prediction, but better not to follow them blindly to the point that you will pay for it just to ride on with their shared predictions.
It’s not just the money you pay to them that is the problem, it is also the fact that you’re paying money to likely lose money. It doesn’t matter if the predictions are given to you free of charge or a subscription, when you stake your money with any prediction (yours or that of a supposed gambling expert), make peace with yourself that you’ve lost. Because no matter what, the probability of losing can’t be denied its place.
