Yes, but you do *not* change the PDF itself. You just enter something in
form fields provided in the PDF. And you can then save the PDF with the
filled form. But when you open it again you will see, that the form
fields are still there and can be changed again - but nothing else,
since you will not change the PDF.

It's like filling a form on a website - you do not change the website

It depends how you interpret "change". If you fill out a form I would
say you change the form from an empty form to a form that has been
filled out. Also, it's natural to think of it as modifying the pdf
file, since the file attributes like "date last modified" will
typically change, while it wouldn't change if you just read the
pdf file without making any changes to the file.

Yes, but the content of the PDF itself is still not changed. So when you
want to edit the content of the PDF and not just fill forms inside a PDF
you need a PDF editor and not just a PDF viewer which can fill forms and
save that.
