I was in a similar situation awhile back for about the same dollar amount. After I was scammed I selected the dispute option on PayPal and instantly called PayPal. The agent I was talking to explained how digital goods are not covered by them, but since I've done many transactions through pp (and being verified) the dollar amount was fairly low he instantly refunded my money for me and expedited the dispute for me. I think the seller that scammed me also got in trouble through them.
Idk if it mattered or not, but I also have a business PayPal account rather than a personal account. That could have helped me too.
Getting scammed sucks, sorry about your loss :/
