Basically, amps tell you how fast electricity is moving. If you have a certain amount of amps running through your body, it will kill you (I think technically no matter the voltage?).

Why doesn’t every battery kill you? Electricity at low voltages doesn’t have enough “strength” to push through your body, as your (electrical) ressistance is very high. The higher the voltage, the higher ressistance it can overcome.

So if you touch say 12 V, only very very few microamps will flow through your body, which doesn’t matter.
When you touch 230 V, now the electricity is strong enough to push somewhere between 10 - 100 mA through your body, which will kill you.
(No guarantees that the amperage numbers here are correct, but the scale should roughly work out I hope).

It all boils down to $U = R \cdot I$ (Voltage = Ressistance * Current).
