A buck converter is a DC-to-DC power converter which steps down voltage from its input to its output. It is a class of switched-mode power supply typically containing at least two semiconductors and at least one energy storage element, a capacitor, inductor, or the two in combination.

You've built a linear regulator. It doesn't matter that your circuit has An indication and a diode, because your MOSFET is operating in the saturation region. It's not switching.

^ Yes, the point of the diode, inductor, and FET is to pump in energy into the inductor based on electrical feedback and in defined amounts given by the PWM frequency driving the FET. None of that is happening

But it works and we always have 5 volts at the load.
