I think it could be some browser configuration, that your search setting points towards wikipedia.

So that if you write "youtube" without the .com the browser will direct you to wikipedia instead.

Yes and also there are many that never use the address bar, they just google names. With this mindset, any text input with a lens icon is a way to reach pages... or sites... apps, stuff, whatever.

I could see iOS safari doing this. It often has a suggested page when you type in the search/URL bar.
