Somewhat untrue by my experience. If you use a custom Rom purposely built without google’s garbage then yes, sure. But on normal devices, even if you don’t log into a google account, android is still going to use google services for at least notifications and location. Google Play Services will still be running in the background all the time sending constant network requests.
Android works just fine without an account, you just cant use any google services.
