Pretty much in any case, PII is sent but what exactly gets sent may differ. For example, Revanced I believe just acts as a wrapper for the YouTube platform. YouTube is still collecting information it's still just you interacting with it just minus the ads. For something like Invidious, YouTube would still be getting information in regards to your IP address in the case of self-hosting or if the connection's proxied that information, but not the same amount or type of information is being collected.
