'Why do `gcc -v` and `whereis gcc` output different paths?

I get the following output when I run respectively gcc -v and whereis gcc:

Apple clang version 13.1.6 (clang-1316.0.21.2.3)
Target: x86_64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

gcc: /usr/bin/gcc

Does this mean I have multiple installations of gcc on my mac ? If so, how do I uninstall the 'extra/unnecessary' ones ?

Thanks

You can trick this by updating a subversion property on the file, perhaps with some name you reserve for this purpose and hide for the user.
