Comparison to bookies is really comparison to betters. Bookies don't really care about winners and losers. They just try to balance the money being bet on each side. Bookies make their money from the "vigorish" --- and a good bookie will win every time. https://en.wikipedia.org/wiki/Vigorish
I wonder if bookies share between them information about where people places the money.
As long as the bets are roughly the same on each side (money wise), the bookies work is done. All he has to do is take from the losers and give to the winners --- and take a nice cut for himself.
