The desktop application is nearly dead on the consumer side (but not quite: Photoshop, Office, etc. are still extremely popular).

But in medicine, finance, manufacturing, industrial design, aerospace, hospitality, and so on, almost everything is native desktop apps. Mostly Windows, maybe a little Linux, very little macOS. Look at what your doctor is using the next time you visit. It's going to be a traditional desktop app on Windows.

Many of these apps are undoubtedly made with Delphi or C++Builder.
