The title sentence never made more sense…
Here was where I read this sentence
Did you know that you can download some Blender Splash Screens projects for free and other projects from Pros(not all are free though)?
Also It’s very informative and interesting to read, watch explanations, by roaming the folders on the left from various artists!
There are nice Tips from Gleb Alexandrov on how to make some of his scenes and other stuff.
Very inspiring 
EDIT: There are other Demo files here: https://www.blender.org/download/demo-files/
