They claim this, but they are lying. Independent studies show the difference is closer to 4%. Google wants you to believe advertisers need all the data collection because it's Google's sole value proposition.

This is a company which fires researchers for publishing the wrong scientific results, probably discard any claim they make based on "their data" after Timnit.
