That’s true for ads from youtube (I have yt premium myself) but not for ads directly in the video.
The yt app from the homebrew store has sponsorblock[1] integrated which can skip these too.
Something else a lot of people don't know is that it can be configured to skip things that are not simply sponsor spots, stuff like filler, intro and and cards, begging for subscriptions, and so forth. That add-on is the single greatest quality of life improvement YouTube has ever seen.
Amazing! I didn't know that. Now I'm starting to wonder why I ever tolerated this noise in the first place...
