Yeah we don't know how many of their simulation picked Brazil or Germany.  Soccer is high variance game played in single elimination brackets.  I'd assume that most Markov chain Monte Carlo simulations won't have the best team win.  These aren't NBA best of 7s.  It's literally much easier to predict a high earning stock than the winner of the world cup.
