Sure, but the discussion isn't specifically about your setup, it's about the advertising claims that a VPN will help prevent tracking. Which is totally bunk.

Tracking with IP is honestly hardly tracking at all. With local network NAT and CGN your device IP will not be unique at all. With modern tracking, your IP will be just another couple bits of entropy, and most certainly not enough to pinpoint traffic to individuals in a robust and scaleable way.
The only tracking protection that a VPN offers is preventing your ISP from seeing your traffic, and making it harder to pinpoint web traffic to you as an individual (assumging you VPN provider doesn't have logs)
There are many, many cases where this is patently false.
For example, correlating different devices by IP is a very common technique advertisers use for establishing cross-device tracking profiles.
You don't know anything about my setup, so you have no basis for claiming this.
