From my experience it’s different servers, but it might depend on your location. It’s the twitch ads that come from the same server as the video stream. Those are harder to block.
If you use a YouTube app then yes, the ads don’t seem to be able to be blocked. Browser based YouTube ads still seem to be able to be blocked by pihole
I was told the other day that pihole doesn’t block YouTube ads because they’re served from the same server?

Pi Hole for me blocked some YT ads but not all. YMMV based on the block list you use. I didn’t get very aggressive but still killed most page ads.
