I used to watch YouTube on my TV without adblocker almost every day, but it's now forcing so many ads that my usage has plummeted. There's always at least two for every few minutes of actual video, they're almost all at least 20 seconds long and unskippable.
The few times I do still watch a video I now have a nice (annoying) little ritual: Click and go back and repeat until the first ad is less than 10 seconds, then watch that to the end, then go back and click again which skips the second ad. It's going to play another 2 ads 5 minutes in no matter what, so I might as well.
