In an amplifier circuit

In an amplifier circuit, are the output current and output voltage always greater than the input current and input voltage?

Strictly speaking, it is the power which is amplified and this is current X voltage so either voltage or current can be increased. This applies over the full range of amplifying devices, magnetic amplifier, amplistat, rotating machine, vacuum tube, transistor, SCR and so on.

No, it depends on amplifier gain in common collector amplifier, the voltage gain is less than 1 and in common base amplifier, the current gain is less than 1.
