I thought bookmakers are delta-neutral. Otherwise, they are gamblers and not really bookmakers?

They try to be, but I think they have to put some of their own cash into the pot with small markets to establish initial odds

They’re market makers. They can’t be entirely delta neutral. There are things called betting exchanges where you can buy and sell bets with other people, and those can be neutral if the operator doesn’t act as a market maker but then there are many situations where people won’t be able to place bets.
