Hi Rajan,
Thank you for reaching out to our API support team.
The metrics returned by this report is associated to the link between an adgroup ad and its asset (Ad-level performance metrics for assets). You can check out this
API documentation related to this reporting for a bit more information.
Should you wish to learn more on the behavior of how these metrics are attributed to this combination, then I would recommend that you reach out as well to the Google Ads Product Support team, via this
link.
Best regards,
