I was watching a video where the narrator stated that changing a file type from .PDF to .PNG doesn’t change the actual file type of the document. Could anyone explain why ?

What you’re saying makes no sense. “Changing the file type doesn’t change the file type”?
Yes it does, otherwise it wouldn’t be changing the file type.
Is it possible that you mean “if I change the file name from “something.pdf” to “something.png” it doesn’t turn the file into a png image.
If so, that is correct, and the reason the file type doesn’t change is that the data in the file didn’t change.
The filename is just a convention. If you name a file .png a lot of applications are going to assume that the file contents can be read as png data. But it might not be. Especially not if you just took a .pdf file and renamed it.
