I knew a professional electrician who always used his fingers to test

clipped on your shirt pocket and always be handy. Later in life he
developed heart problems, and after several open heart surgeries, it
killed him. I always wonder if all those shocks were the reason?

In a way. All those shocks over the years built up his resistance to
electricity such that the defibrillators in the hospital had no effect.

Your body does not build up a resistance to electricity. Your hands
can be dry and more fibrous which gives them more resistance, but
this has nothing to do with "immunity" to electricity.
