It's an ambiguous question, because technically all signals are analog. The short answer is no. By asserting they are logic gates, you are supposing digital logic criteria and analysis: high impedance input, nominal output impedance, the transistor's operating regions are either saturation or cutoff, and the I/O signals are analyzed in discrete steady-states. Digital signals are applied to logic gates as the distinction of "digital" establishes the above signal criteria and circuit operation.

Why XOR and XNOR gate is not known as universal gates?

All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).
