The pro moniker with most equipment means that somebody who makes money from using such equipment will likely use it. Cameras also use similar distinction. Everybody using a full-frame camera is not a professional, but most professionals use a full-frame camera.
But most professionals are not using "Pro" laptops. They use basic consumer laptops, because they don't have the need for anything else: it runs Outlook, Excel and IE fine. A professional photographer probably has higher computer requirements than most professionals, for that matter. And yet when they needed end of line MacPro/Power Mac a decade ago, the photographers that I know are very happy with oldish iMacs these days.
My very own example: Tomotcha. An old MacBook Air from 2011 is way more than I need to research teas, buy some, write blog posts or answer to customers. It's also enough to work on the underlying Python 3 codebase (not that it's very long). That's just one usage of my computer, but it certainly qualifies as pro.
