That would imply a collapsing somewhere between the two.
Also, would the body, being mostly made of water itself, really get crushed instantly? I would certainly expect the pressure to squeeze all the air out of your lungs.
I know nothing about how the body behaves under high pressure.
"psi" is pounds per square inch, and a human has ballpark 3000 square inches of surface area.
So to get a (very) rough approximation, picture what would happen if you squeezed a human with 3000*1892 pounds of force. Or try not to picture it, because I imagine it being pretty gross.
Industrial divers / welders / etc get all kinds of training to avoid that stuff, for good reason.
That said, if divers are slowly "eased in" to the high pressure environment, it is actually possible to equalize pressure slowly and acclimatize. Though 1.3km would still likely be beyond the limits of that https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5110125/
