Literally unexplainable behavior: After re-install

I installed Windows 11 on my PC.
I did not install any drivers, only whatever Windows Update installed.
Wi-Fi works. Bluetooth did not work.
I'm aware Windows Update installs some basic drivers.

I went and installed a few Bluetooth drivers (took me a few tries to get the correct driver). Bluetooth now works.

I felt uncomfortable with random drivers installed. So I re-installed Windows 11 again from scratch on the same PC and SSD.

After re-installation, I did the Windows Update and I did not install any additional drivers. But both Wi-Fi and Bluetooth works already.
I didn't even install the Bluetooth driver after re-installing... why does it work now and not before?
