The sink is pretty thoroughly grounded in most residences.

=====

No ground on my sink via the ABS drain pipes or the PEX supply tubes
either.

Then it's grounded though the water in the pipes. And the ground wire
to the disposal.

To get a shock you need a voltage _difference_. Not gonna happen with a
garbage disposal full of water.

==================
Geeeez! I hope you don't actually believe that one.
Water is not a good or reliable ground. Pure water is a complete insulator.

Not acceptable, not safe and will not pass the safety requirement in any
code (use of water for ground). Copper pipes can make good conductors but
not to be relied on in most cases.
