That's around the time of the Pixel 2 XL, IIRC. They wouldn't get base OS upgrades, except in emergencies. I bet they are still getting updates Chrome, Gmail, Maps, and all the other core functionality from Google, though. Notably, the most security sensitive element is the system web browser. This also gets updated even when the base OS does not. Android and iOS are different worlds. For most users, the update lifecycle differences are not large.
