So as you see, when the book has an identical record to you, they kick your ass big time by winning way way more than the player, and the ONLY reason for all this, and the only reason why 97.6% of players lose, besides the chasing, the bad money management, and so forth.. is the vigorish..

It is just about mathematically impossible to overcome the juice for the average gambler over the very long haul
