This idea that most of the guys betting on sports every weekend are “pretty much breaking even” is wrong. Anyone can get lucky on a long shot, but as soon as you demonstrate the ability to get the real edge – the one that understands that odds pricing is the only thing that matters, you are kicked out for life.
Because the good ones (everyone trained by Abdulmanap basically) are always heavy favorites. You will have to risk large sums to win a pittance and all it takes is one loss to wipe out all your previous winnings.
