I think clarity on the projects / names would be helpful. There's no
project called MinGW32, there's mingw.org and MinGW-w64. We're a
friend-project of the latter and have no relationship with the former.

When you say you downloaded a fresh copy of mingw-w64, do you mean one of
the mingw-builds supplied toolchain packages? If so, as Jonathan Baecker
said, you don't need that just use pacman to get everything instead (though
see below *)

MSYS2/MinGW-w64 consists of two or three systems, the MSYS2 system itself
(the native sysroot for that would be e.g. C:\msys64) then a 64-bit
MinGW-w64 system (sysroot at C:\msys64\mingw64) and a 32-bit MinGW-w64
system (sysroot at C:\msys64\mingw32).

You don't install "MinGW" except via pacman, then you'll have a
C:\msys64\bin folder and maybe a C:\msys64\mingw64\bin and maybe a
C:\msys64\mingw32\bin folder, same for lib folders. In bash, we bind mount
/bin to C:\msys64\bin since some unix things expect that, all of the same
applies for lib).

For MSYS2 gcc, install it with:
pacman -S gcc
Jonathan Baecker told you how to install MinGW-w64 toolchains. Also, see:
https://sourceforge.net/p/msys2/wiki/MSYS2%20installation/
(* below) If you want to use MSYS2 purely as a bash prompt/unix-y shell,
then that is fine. In that case, you'd never install any pacman packages
that are prefixed by "mingw-w64-" and would instead download e.g. a
mingw-builds supplied toolchain release. I'd suggest putting that in
/opt/mingw32 or /opt/mingw64 (so C:\msys64\opt\mingw32 or
C:\msys64\opt\mingw64), then prefixing its bin subfolder onto your PATH as
appropriate (in ~/.profile for example).
