Do you think these predictions are reliable?
It's just the same as the usual sports analyst predictions - nothing special.
Supercomputers or what you call them, have no way to predict what's the "exact" thing that will happen since there are game scenarios that can happen in actual games. What they give as a set of predictions is just a product of their followed algorithm.
I'd rather stick with a real sports analyst that discusses the details of their prediction.
They are only basing on the data or information found in cyberspace. The actual conditions of the game and other factors such as the current skills of the athletes, their game plan and others may not be included in how these supercomputers or AI will determine the outcome of the game. But reading their predictions may give you good insights on where the game is heading at. There is nothing wrong in reading those predictions.
