"Who's Andrea Immer?"
"Wine guru I'm besotted with. Of course I've only met her on TV."
"You and a million other wine geeks, probably," Jack jested.
"When my book gets published I'll be able to afford the rare Burgundies to romance her."
I don't understand what Jack meant by saying "You and a million other wine geeks, probably" . Probably what? It seems to me an incomplete sentence and I can't guess what Jack was trying to say?? Can anybody guess?
