I have been struggling to understand the window functions. I understand its use case like when you want to rank countries population per continent however the syntax is so weird it doesn't make any sense what actually happening

How does the sql server process this? does it run on every row? is there any benefit of using it over subquery?

sorry if this question is too dumb :(

I've been working with SQL off an on for 20 years and never heard the term window functions before. TIL.
