Actually it’s both. You can have as high of a current as you want, if there’s no high enough voltage potential, current simply won’t flow. Any battery can push more than few amps of current easily, but voltage potential is not high enough to push it through your body. In general you are right, minimal amounts of current are enough to cramp a muscle, however it takes a lot of pushing to get to that muscle.
you need at least 100V DC or 50V AC to break the skin’s resistance, then there has to be at least 30 mA. which isn’t hard to do with a body resistance of a couple kΩ.
fun fact: there’s 400 Volts between the terminals laterally. that’s gonna be one hell of a cardiac arrest.
Current is what kills the heart. AC is more dangerous and it can cause ventricular fibrillation.

While you are right that it’s not as simple as just current, batteries are typically not AC.
