This seems too good to be true. If they could actually predict football results with better-than-random accuracy, then why wouldn't they just use this themselves to make loads of money on betting markets?

I don't think they're claiming their statistics-based predictions are necessarily more accurate than the bookmakers' odds

Good point, I suppose "69%" accuracy doesn't actually mean that much unless you consider the odds.

I'm pretty sure I could predict Real Madrid vs. my local home town team with better than 69% accuracy, but that doesn't mean much

Well sure, but there are over 2200 games per month and less than 3-5% are the kind of games you are talking about. Super good team vs terrible team (assuming your local home town team is not Barcelona)

It has 69% accuracy, that means you still lose 31% of the time.

69% is a huge number in terms of sports betting. Typically to be profitable you need to be in the 52% - 56% arena to be profitable, so this is significantly profitable
