“A professional sports bettor like Voulgaris might place a bet only when he thinks he has at least a 54 percent chance of winning it. This is just enough to cover the “vigorish†(the cut a sportsbook takes on a winning wager), plus the risk associated with putting one’s money into play. And for all his skill and hard work— Voulgaris is among the best sports bettors in the world today— he still gets only about 57 percent of his bets right. It is just exceptionally difficult to do much better than that. Silver, Nate. The Signal and the Noise (p. 256). Penguin Publishing Group. Kindle Edition. ”
