Google Video algo

I have noticed recently when I submit a search term & go to the "videos" tab in Google, video results on the first 2 pages are website-hosted videos. Keep in mind, I used pretty broad search terms that should return thousands of YouTube results.

Is Google really bumping unique, embedded content above their own YT video results? I tested 3-5 search phrases in a single session, so not a ton of research here. & it's worth adding this was NOT in the main serps, but rather the "videos" tab serps. Is this their new norm for the time being? & is it worth embedding videos to pages across your website optimized for these results?

Yes, You are Right, it happens even for very common search terms, and always add videos on your and optimize them, the upcoming trends are all about video marketing, gif and videos works more than image now, I see people using gif and videos all over in their websites, it's good for users too, as the retention time increase on your website.
