YT Revanced is not a 3rd party client. It (and all vanced patches) work by taking the original app and patching the code directly, often simply to bypass sections of it entirely.
Let’s take backg ground playback for example, the app has that functionality but it checks if the user has a premium subscription or not before allowing it. Revanced simply removes that check by jumping over the code and always returning true.

Yeah it works more like how cracks used to work back in the day.
