"Win" money

So I'm a bit of a newbie, please bear with me.

I have an account on bookmaker, and I bet $1 on the 1 horse in the 7th race at Del Mar.  The horse won and paid $4.60 to win.  So shouldn't I win 4.60 on a dollar bet?  Bookmaker said I won $1.30, which is my original dollar back plus 30 cents.  Can someone explain what I am missing?  Thanks.

bookmaker is right   you "won" 1.30 plus the dollar you bet meant total take back was 2.30 on your wager- -you were credited 2.30 back in your account which was the $1 win mutual payoff so you are good to go
