Most products struggle with YouTube ads to be fair. They are using the same endpoints as the actual videos so blocking them blocks the video. You can try putting a . after youtube.com i.e. youtube.com. which stops the ad playing but also signs you out.
I would rather have PiHole than not. It takes about 30 minutes to install (I had an old Celeron machine lying about that I install Debian on) and about 1-2 hours of blocking/unblocking anything that slips through the cracks e.g. many of the lists block the referral sites that Quidco and Topcashback use.
