Does Pi-hole block YouTube ads?

Expected Behaviour:

Ads should be blocked when I visit any website

Actual Behaviour:

Ads are not being blocked. Tested on Youtube.

I was initially not able to get the DNS Server changed on my router, so I set up the Pihole as the DHCP Server as well and turned off DHCP on the router.

Based on what I can see in the console, queries are being logged and there are active Clients. but I don't see any ad requests being blocked, and websites are still displaying ads.

Not sure if it's related, but I am unable to finish a sudo apt get update on the Pi itself.

I tried searching for help on the forums regarding Youtube ads still getting through PiHole but the last ones seemed several years old. I'm currently in a battle to block adverts without then blocking the video I want to watch. I'm blacklisting the domains that start with R then a number from google but as mentioned in another thread it seems that the adverts and videos are piped from the same source, so either I get adverts and the video, or I get the first few seconds of the video then the perpetual loading notification

I'm expecting that my pihole should be able to identify the adverts and drop them off, or filtering unexpected extra connections, since there's always a pair of requests in the query log that are veeeery subtly different. I've black and white listed as I've gone along and it seems like it alternates between the addresses feeding videos or adverts (sometimes I even get the adverts but not the video / only the first 5 seconds of the video). Are there recommendations for additional settings/setup to sort this at all?
