I don't think that's the case at all. As far as I know, advertisers never receive personal information from Google. Google hordes the personal information and shows advertisements (provided by the advertisers) to their users, using their personal information. It would be rather contrary to their interests if they were to send their user's data to other parties. They'd lose their commercial leverage and their ad network would become less valuable.
