Yeah, usually when someone parrots the "it is the amps that kill you, not voltage" line, I have to remind them that the amps depends on the volts. A car battery is capable of hundreds of amps, but if you touch the contacts with your hands, you won't feel a thing, because the voltage is too low to overcome your body's resistance. I imagine if you wired the leads to your tongue, your tongue would probably explode though.

It's advisable to remove rings if there is any way they could short across a car battery. The battery has very low internal resistance, so you can get a sizeable part of a kilo-amp flowing, which due to "P = I^2 R" can generate an impressive amount of heat. In fact some owners of certain Russian motorcycles with a propensity (Ural, Dneipr etc.) were able to weld bits back on in the field by using the carbon contact breaker points to do rough arc welding. Which doesn't contradict you at all - I'm just saying treat car batteries with respect.
