Where did all of that come from? It's fantasy as far as I can tell.
I have never heard "Page-outs refer to a file-backed page being committed to disk."
I think you are confusing it with a file cache or buffer cache commit interval.
A page out is when a page of memory is written to disk ("paged out") so you can use more live memory than you have physical RAM. Fun fact: the kernel is smart enough to not page out the page in code.

That's a distinction without a difference - the file/buffer cache stores memory pages. They are simply file-backed pages.
