I don't really watch that much youtube but now that my son watches some cartoons on it I've subscribed to premium so he doesn't see any ads. I think it's ok to pay for youtube as it arguably provides a useful service. I also know that I'm in a privileged position to be able to pay for youtube premium, so my comment is not about whether ads are inherently bad or not, just that you can watch youtube without ads if you pay for it.
