Yes mechanically, like that the sign on the Pokie that says "THIS MACHINE GUARANTEES TO PAY OUT 85c IN THE $" what it is REALLY saying is that "this machine guarantees to take 15c from every $ that goes into it , rain or shine"
Same with the "other" machine the name of the game is to slowly cream off 15c in the $ like clockwork........ one person or more winning on one or even 100 particular races is irrellavant really isn't it?
