it will download the youtube page and remove trackers and telemetry. but google can still correlate traffic from ip to other identities of yours, I am not sure if by using invidious whereby you download the webpage from the instance and the video feed directly from youtube ( if you are not using proxy option in invidious) is more private than using Freetube and NewPipe which download both the feeds from youtube. only someone from google can tell if they track connexions to youtube "video servers".
