Newbie - Voltage - shock of 9v battery vs. 12v car battery

Hi, I'm just starting out self learning electronics and have a
question regarding voltage. If a volt is a volt is a volt, that is 1
volt can push 1 coulomb of electron flow (1 amp) through 1 ohm of
resistance, than all volts are the same pressure, hence why is a unit
of measurement. So why is it if I take a new small 9v battery from any
convenience store and shock myself with it, the shock of this 9v
battery is MUCH smaller then a shock from a 12v car battery ? It
can't be the 3v difference. Is it the amount of current ? But then
since there is not resistance between myself and the battery, the 9v
would produce 9 amps and the car battery 12 amps again, not that much
difference but the shock is a huge difference.

And no, I'm not into shocking myself but it happens...

TIA
