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. |
