Mac Anonymization Question

Hello I have a question. If I were to use a whonix vm connected to a whonix gateway OR using fedora or debian vm connected to the whonix gateway, is my my mac address automatically randomized or do I have to follow the guide listed in or Anonymizing your MAC Address | Qubes OS ?

You should not worry about the vm’s MAC address, because only the machine MAC address is visible outside your Qubes-OS install. So if you follow the Guides you linked, or use WiFi, your MAC is randomized, no matter how you connect inside Qubes.
