It is correct, but if standard libs are linked statically and project does not require pthreads libwinpthread-1.dll is not necessary and should not appears in dependencies.

In my memory, I think lib winpthread is a hard dependency that you can't remove. You can ask mingw64 devs for further question.  :)

It is a hard requirement when building GCC when several libs are built.

The OP might try the new MINGW GCC using non posix threads and see if the exe is smaller.

Edit: Add link https://winlibs.com/ See the ones with MCF threads

Standard libs are under authority of the GNU, not MinGW64-w. It is why winpthread appeared actually.
Now it looks like this (see attach)

exe size is not pumped by thread libs, actually they all are compact.  I suppose bloating  is the result of the implementation of the C++ std functionality.  Even with dynamic linking a lot of stuff is in-lined and generated a solid footprint.
