No they don’t. They sell the ability to display ads to users in a targeted fashion. The user data is how they do that and is their moat. Their entire market advantage is they don’t sell the data, instead you have to continually let them decide who sees your ads to leverage that data.
Google goes to great lengths to make sure only they have this data.
