This is just plainly false in case of Python.

Rust is already "native" so Cargo doesn't need to do anything.

Python has the logic to do native builds baked into pip and friends, so a Python package can just specify what to build in the manifest. But it also allows for precompiled wheels, and most popular packages do them for all major OSes, so users rarely need to actually build stuff in practice.
