Stories like this (And Paul the Octopus, who I see was mentioned already) are exactly the same thing. Thousands of people are trying to using deep learning (i.e. stats), or other crazy methods as in this article, to make predictions. Of course every now and then one of them is going to work better than expected. This would be the case even if people were simply using random numbers. But we ignore all the ones that fail and give heaps of attention to the Pauls.
For instance, you have a statistical population of one hundred men and one hundred women: you collect as much data as possible about them - as many features as possible, actually - until you find something which happens to be statistically significant for your group (eg. salt consumption). Then, you publish your results, pretending that the feature you found was the original hypothesis for the study ("Our study confirms that salt consumption is higher in males.")
'Salt consumption can increase the risk of liver consumption for middle-aged males of African descent'

And here's a slightly more exciting description of a talk one of the authors gave on that topic at UMass Amherst last year:

EDIT: I was too stupid to realize that the paper linked above actually supports the parent's opinion, i.e. the idea that successful predictions are statistical artifacts, contrary to what I was thinking earlier.
1. They made the predictions well before hand and released them to the public.
2. As the article stated, they also did the same thing with Hockey, Derby, and Academy Awards.
There was absolutely SOME luck involved, however, because I don't believe that, for instance, there is zero randomness in the World Series, which would have to be the case if one could absolutely predict it accurately.
[UPDATE: to be clear, I'm assuming that Unanimous didn't make thousands of similarly high-level predictions, and then only report the ones that did well. I think that's a reasonable assumption, because there aren't thousands of high-level predictions on the level of the Oscars and World Series.]
[UPDATE 2: I just registered at the site. It appears that many people can ask the same question, many times. The same question looks like it can be asked, in fact, many thousands of times. If they were simply cherry-picking the one answer out of thousands that was correct, then this is p-hacking. However, the press release is listing questions asked by prominent entities such as Newsweek and TechRepublic. There aren't all that many of such entities asking such questions of UNU. So the water is a little murky, but it still looks like UNU is doing something impressive.]
(no seriously, great comment)

That's pretty different than sending out thousands of random predictions. This was ONE prediction about MLB.
