Showing page numbers in any version of Pages introduced since Fall 2013 is purely voluntary and one visits the View menu and selects Show Page Count. That produces a floating panel at the bottom of the document that initially may have a character count. You click the ↕︎ symbol on the right side of that panel, it opens to display a list of choices, and you select pages. That floating panel now shows your document page count:

Once you have selected the above, you can also reference the page count via:
Show word count and other statistics in Pages on Mac - Apple Support
If you select a paragraph and want a word count, you click that panel again and it shows counts on the panel for words, characters, etc associated with that selection.
You also, depending on preference, can insert page numbers of the form n of m in the header or footer of your document to show page n of m total on each page.

Pages was never designed to be a Word clone, so you simply won't find most word features or that page reference in the lower left corner of an open Word document status bar that is available without hunting for it.
Apple is not competing with any other word processing vendor on features. One can use Pages, or any number of other word processing applications on the Mac based on your application and production requirements. Want to use Word on Windows, then by all means do that.
