Varistor is a semiconductor diode whose value of resistance depends on voltage applied, its not a resistor.

Varistor is an electronic component with an electrical resistance that varies with the applied voltage. It is also known as a Voltage Dependent Resistor (VDR).

The forward and reverse biased states of a diode can be compared to a variable resistor. A forward biased diode will drop only .3 or .7 V.
That corresponds to an internal resistance in the anode that drops from several Kilo-ohms at the point where conduction begins to several ohms where a diode is conducting heavily.
In the reverse bias state, resistance will be in the Mega-ohms until breakdown voltage is reached.

If referred as a semiconductor diode or a voltage dependent resistor, does it sound correct? I doubt.

A semiconductor diode with resistance dependent on the applied voltage.
