Hardly. There's 7 continents (~3 bits of entropy), but dozens/hundreds of camera models this technique (6-8 bits). And it's hardly the only media forensic technique out there. There's ways of extracting the time of day without metadata, manipulation software chain, the lens used (sometimes down to make and model), and tons more. Before you know it, you've put a big dent in the ~33 bits needed to pinpoint a specific person.
