I feel like you might be confused about the statement. One platform gives 58% odds, the other gives 64% odds. This is obviously high, but also very far from virtually guaranteed. In 100 trials, we’d expect recession in ~60 events. There is no secret math hidden here, it’s just that.

And if you play Pokemon you know anything not 100% is 50%.
