It does block Youtube ads but very poorly. Sometimes the ad plays but a refresh immediately removes it, other times it can take multiple refreshes. It's not perfect like it is when i use Firefox or Opera so I stick to Yputube on those and Safari for general browsing.

Sidenote: Also Gmail is insaaaaaaaaaanely slow on Safari and a lot of sites just don't format well or ad blockers completely break the site. Safari is by far the worst browser on Mac for site compatibility and also extension selection but I use it for better battery life when not plugged in.

It does, at least for me (using free AdGuard).

This seems to be possible, not entirely sure how though.

Not being able to block YouTube ads is always used as some kind of gotcha, but for me the trade-off is easily worth it.

Besides, blocking YouTube ads seems a lot scummier than blocking regular ads. Ad least some percentage of that ad revenue goes to the creator of the video you're watching, and not to Google. It's why I'm happy to subscribe to YouTube Premium.

In practice safari blocks all ads I can see, youtube ads might be an exception but it's one of the few services that is 100% worth paying for, considering how crucial they are, how much time most of us spend watching content there, and how fair their premium offering is.
