It's a leak of location information, which is what this sub-thread is about. The location information was only inside of Google, and now the advertiser has it.

It's also not "one in 6,000 people" if it's someone who signs up for some service via the ad. That particular someone might not realize that the service knows their location.

The point in 1:6,000 is that whether it's ad targeting or just regular internet traffic, there isnt enough specificity to "leak" data about the person. You can split hairs over, "Well what of they join that 1:6000 with other PII" and it's the same with Geo IP. The user gives up that data but it's not different than just visit the page normally.
