Except Wine cant cover all of Windows (partly due to fault of Windows). I can't run UWP apps for example. Windows is not a good operating system but if you need it. WSL creates way more intuitive working environment for you. So even if you can run multiple Linux OSes in Linux you can't run Windows as easily you can do linux on Windows. So OPs statement is not incorrect.
I've never seen a good UWP app. My biggest issue with Wine is that it can't run anything that needs a driver. That means any hardware with garbage Windows-only control software (hello Roboteq) needs a proper VM.
