If you're counting words on a page for SEO, you're not really in the right mindset. Google's algorithm is ran by AI. Yes, back in the day when you could just keyword stuffed "shoes" a bunch of times for a shoe e-commerce store... you could get away with it and game it a bit... but these days are long gone.
What you should worry about:
Making your page better than all of the pages that currently rank on Google's 1st page.
Why does your site deserve to rank over them? Because you stuffed your topic a bunch of times? That's silly.
Make amazing and useful content and build relevant/high-quality backlinks from reputable sources and you'll do well.
