True, in a sense, but misses some nuance. Current is pulled, not pushed. Volts provide the electromotive force that allows the current to flow in the first place. Considering Ohm’s Law (V=IR), for 8 Amps to be pulled by a human body at 110V, the body would have to provide a resistance of only 14 Ohms.
A quick search shows humans can range from 1000 Ohms when really wet up to 100,000 Ohms dry. I’m assuming this is just in regards to skin, because another result specified 300 Ohms inside the body. Let’s just look at the 300 Ohms, and we’ll say 8 Amps * 300 Ohms = 2400 Volts. 2400 Volts to pull less current through the body than your average hair dryer pulls at 110 Volts.
Another way to look at it is a car battery is 12 Volts and has the capacity to provide around 500 Amps. Touching one terminal with each hand won’t kill you. We don’t come close to drawing the 500 Amps the battery is capable of providing, as we’re only pulling 12 V / 300 Ohms = 40 mA at worst (but remember that skin provides extra resistance beyond the 300 Ohms, so really we’d be pulling much less). It only takes a couple milliamps across the heart to kill you, but what little current flows through you is taking many split paths through your body, so only a portion of that goes through the heart.
