Google search does have a Videos tab showing video search results.
I just did a search for "ASCII table" and there are 4 videos not on YouTube in the top 10 videos (2 of them on a website called "ASCII table", one on "science buddies", one on reddit).
(In fact this is why I don't like to use this tab: the video might be on a random website and the video might be somewhere down the page, while the website is not optimized on mobile.)

I feel the way you do, I never use that tab because often the videos shown there are hosted on shitty websites. I wish it was restricted to YouTube so I didn't have to go to YouTube to search YouTube.
