Yes, of course they read it, they must get it into your screen, that counts as "using data."
This is entirely clear:
No. There are no ads in Google Apps Services or Google Cloud Platform, and we have no plans to change this in the future. We do not scan for advertising purposes in Gmail or other Google Apps services. Google does not collect or use data in Google Apps services for advertising purposes. The situation is different for our free offerings and the consumer space.
