Serious Where do info youtubers get their info?

[DREAMEROFGREATNESS]

Whenever I try googling a lot of irrelevant answer pops up so I was just curious to know that how do these youtubers who make informative videos and are run by individuals get there info from? I tried doing research but the best I can do is watch youtubers who made video about what I'm looking for but what I want to know is where do they get to know? Cause google search is already broken.
