These supercomputers are created in the concept of probability made easy, their analysis relies heavily on the data provided on their database, and some circumstances are not within their scope like if the major player of one team is injured and cannot play at the last minute.

Another one is in boxing, the Haney - Garcia fight. In all probability humans and AI point to Haney but when it comes to the fight night there are tiny details that are not taken into account, which resulted in Garcia beating Haney.
