Why would anyone just watching videos on YouTube care how many people have seen the video? You enjoy it or you don’t, how many other people have seen it doesn’t change the viewing experience at all.
The only people who would care are YT themselves, the creator, other creators, and advertisers.
I don’t know why they even publicly display the view count.

For the same reason online shops show "Most popular" items and ads say "trusted by X people worldwide". People on average apparently like feeling being part of a bigger crowd. If that doesn't make sense to you, you're probably in the minority (which by that logic shouldn't bother you).
If you're looking for a tutorial, and one video has 5000 views and 4000 likes, the other has 5000 views and 2 likes, that really doesn't help inform you about which video might solve your problem better?
If I knew why people didn't like it, perhaps. Videos get liked or disliked for all kinds of reasons. Typically I'll find several tutorials that look like they may be relevant based on the thumbnail and title, and then skim through each one very briefly to see if it looks as though it is what I'm looking for.
I've heard that it's not actual dislike count, but extrapolated data contributed from people who installed the extensions. But I've also heard that some channels have compared it to their actual dislike count and it only differs little.
It's social proof, specially before you start watching. And after watching it's still interesting in a "huh this trailer got 5M views, didn't know so many people were interested in it" way
