I’d be surprised. It’s extremely expensive to store, process, and stream that much video data. Google also doesn’t, as I understand, sell data to third-parties; they use it to target ads for their own ad network, and while I’m sure viewing habits contribute a lot towards making that targeting more valuable, they’re still dealing with extremely high operating costs, and those have to be at least somewhat balanced with actual direct revenue.

You can try Vinegar though. It’s a paid plugin for Safari but it blocks the ads and works wonders. It’s doesn’t take too long to get used to using Youtube on Safari once you stop seeing the ads. Give it a go
