True, at a particular frequency. But, inductive impedance increases with
frequency. Capacitive impedance decreases with frequency.

The parallel resonant circuit may have extreme impedance, but at higher
frequencies it may have a very low impedance, especially if the resonant
circuit is a high-C circuit.
