I think that is a huge exaggeration. I can't think of any rational reason for why you would think so poorly of macOS.^^ Mac OS is worse than the worst Microsoft ever let out of its stables (Windows ME)
It seems to me that macOS is just as powerful as Windows or Linux. If you do all your work online, the operating system you choose makes little to no difference, and Mac fits the bill. And I know for a fact that many companies and startups of today (in Bangalore for example, and also including my workplace) stick to Mac for coding and highly technical work. And all the designers use Mac too. Your own experience at your workplace (of people preferring Windows) might be an anomaly. AFAIK, a lot of people love Mac.
But that isn't to say macOS is better. In my opinion, the market for operating systems have come to a saturation point, where unless you're facing a computer-breaking technical issue, all operating systems essentially do the same thing. The same goes for Android and iOS. Either operating system can do (almost) everything the other can, which is fine enough for 99% of people, tech people and creative professionals included. The only difference between OSes is with the UI and the price of the hardware that comes with the OS.
I myself have been using macOS on my MacBook for over a year. I work exclusively online (not a lot of technical work) and I love the laptop to death. I personally prefer the UI of macOS to Windows, especially due to UI elements like the dock, Expose and hot corners. This opinion has changed a bit with Windows 10, where introduction of similar UI features make it much more attractive to me. Also, I use an Android phone (which I prefer over iOS for UI reasons) and Windows on my desktop PC (which is good for gaming), so please don't accuse me of fanboyism.
Mac OS all versions combined has less market share than any single version of Windows OS including Windows XP which dates back to 2001
That is of course expected since Mac has always held the "premium" share of the market. And it is effective in that market. You can't really compare it to Windows XP.
Also, when it comes to laptops, I really think that no laptop really approaches the keyboard, trackpad and overall build quality of the MacBook (the Dell XPS 15 comes close). A lot of people share this opinion and this is certainly a factor for macOS to hold a very healthy share of the market.
Your statement of "The only people that still need Mac's are the teams working on Mac OS and iOS software" is wrong as there are a lot of people like me who like macOS, if only for UI preference.
