I don't think it is fair to say it is not possible. There is an AI system out there that has correctly predicted the superfecta for the Kentucky Derby based soley on user predictions.

Also as an aside, correctly predicting a superfecta happens quite a lot, and it is hard to tell from sample size of 1 if this was luck, skill or a combination of both. Probably a combination of both - their algo may have reduced the odds to 200-1 for example, and luck did the rest.
