I’ve had a Google, and it’s apparently liquid metallic hydrogen. So, not liquid hydrogen as we know it. It’s in a different ‘phase’, or form that depends on the pressure and temperature (like ice, water and steam are different phases of water).
On Jupiter, this hydrogen is liquid metallic hydrogen, a bit like the inside of the sun, but at a much lower temperature.
Not much I can add to this, but that it’s the huge mass of Jupiter that gives it enough gravity to create the pressure that forces the hydrogen into this state.

The rest seems to mostly be helium, yeah, but a huge amout of liquid metallic hydrogen, well above 70%.
