    Terms that you search for
    Videos that you watch
    Views and interactions with content and ads
    Voice and audio information
    Purchase activity
    People with whom you communicate or share content"

Google does write "We don’t show you personalised ads based on your content from Drive, Gmail or Photos." That's a narrow exclusion. That info could still affect your YouTube selections or search results.
