A huge amount of educational content is available on youtube. If you decide to learn something then all types of content are available on youtube.

When you enter any learn queries on Google like that
“How to learn SEO”
“What is SEO“
“How to learn the English language”
“What are SEO ranking factors“
So video content takes priority rather than other content.
Google thinks, tutorial or educational content in the video, you will feel good.
Because some people feel difficulties to understand written content.
If you will get content in your local language or at least a speaker will look ahead to you, and also show you some slides, so it will be very easy to digest you.

Reviews
If you have to go to a restaurant and have used your mobile, then hands-on review has become an important category.

Because when media available to every one reach, when the camera reaches to every one pocket, then people started to share their opinions.
As you share your opinions on Facebook, like that people share their opinion by youtube channel.
so it has a great benefits.
for example. If I want to purchase a mobile, and if I search for a review on Google and a person who purchase this mobile before and used it.
He fells this mobile better or bad he make his review in video formate and uploads a video on youtube.
so this video can be trigger against my search query because Google Thinks if you are going to purchasing a mobile then it is possible with the reading of mobile review, you are trying to watch review in video formate.
In this situation video content trigger to you in the search query. And mostly it remains better.
Rather then you read a long review, you listen to a 2-minute talk of anyone. possible these 2 minutes talk will be understood for you.
And which question you are searching you found in those videos.

And the last thing is the feedback. This is also a review category. The Catagory is like this, for example, you have bought something, and you fell it good or bad, or you eat a meal in a restaurant and want to share its taste or for example, you have any opinion against Govt policy.

So against these feedback queries are some triggers, which show you results in video content.
Rather then, there are also many scenarios, where Google thinks video content will be better as compared to other content.
So in Google video content rank on the 1st page.
Purpose.
The purposes to explain all these things is that, if you are writing your website or writing your ebook, then if you started to upload your content in video formate.
For example, where you are making a guide How to purchase a mobile
