Gravity can't crush you all by itself. Even if you were being sucked into a black hole, gravity doesn't crush you.
Actually, if you were sucked into a black hole, gravity would stretch you out.

The only reason you think about gravity crushing you is if you are pinned against a surface, such as the solid surface of a rock planet. The pressure of Jupiter's atmosphere would crush you as you fell to the center of Jupiter or until you met gas more dense than your body.
That is correct.
