Where do you think Google would rank its own support, help, etc., contact pages and info if not at the top of searches like the ones you mentioned?
It's not where the _would_ rank ... it's where they currently _do_ rank.
In my test, the AI Overview produced accurate information ("Google does not offer phone support for account recovery") but none of the other hits on the first page say anything like "Phone support calls are always fraud. Google will not call you."
