Is that a commentary on Python, or the average undergrad student?

Python has a compiler. The "c" in .pyc files stands for "compiled" and Python
has a built-in function called "compile". It just happens to compile to byte
code that runs on a virtual machine, not machine code running on physical
hardware. PyPy takes it even further, with a JIT compiler that operates on the
byte code.

How is that relevant to a language being taught to undergrads? Sounds more
like an excuse to justify dislike of teaching Python rather than an actual
reason to dislike Python.

The programming language purists should know better than that. The choice of
which garbage collection implementation (ref counting is garbage collection)
is a quality of implementation detail, not a language feature.
