I’m no expert but in my experience developing mobile applications & push notifications, I’ve only registered a device for notifications (and subsequently sent notifications) if the user opted in. Based on my own experience, I would say if you didn’t enable notifications for a particular service or app, they don’t get sent.
The app developer will still send them to Apple / Google though so the data will still be available to snoop on.
Dunno how it is now but it used to be that Apple would tell you which push tokens (recipients) were rejected (app uninstalled, push disabled for your app, or you stored a bad token to begin with) and you were supposed to stop sending to them, with the implication that Apple would get upset with you if you kept sending to rejecting tokens for too long.
