How ESR is too high displayed in muruta tool

The 1uF ceramic capacitor's resistance is 7.8 Ohm at 100Hz according to the graph, so at 0Hz, its resistance(or ESR) will be much higher. Is it true or I made any mistake in reading the graph in muruta tool?

The impedance of 1uF at 100Hz is 1.59k ohms so why is 7.8 ohms too high? At 0Hz the impedance will be infinite.
