In the experiment video there's a bubble of water in view of the camera. The bubble shrank a bunch before the light bulbs, bottles, etc... were crushed. Those items were crushed because they were full of air. Air is compressible, and fluid is generally not compressible.

A human has around 5-6 liters volume of air in lungs and other respiratory tract, skull (sinus, nose, mouth, ears, throat), intestines (where farts come from). That air volume will be (almost) instantly compressed to around 0.3% of its original volume, via water suddenly pressing in at around 5000 psi, as the body collapses down unevenly - instantly collapsing in air-containing areas but not in adjacent non-air-containing areas. The water pressure causing that collapse is uniform, but the body's resistance to pressure is not. I would guess that fat has least resistance, muscle a bit more, muscle with bones under it (ribcage?) a bit more, skull has more resistance, etc. Not sure of pre-existing orifices in skin will make any difference. Anyway, if pressure is uniform but resistance is not as body is instantly but unevenly collapsed, seems a recipe for a shredding.
