The issue with jumping is it's never a guarantee. People have survived falls from ppassenger planes before at flying altitude. If you wanna know physically what would happen though, there's a 99% chance your bones shatter from the force of impact instantaneously. You would sorta become like a puddle. IF you survived, you'd have every bone broken most likely (though some people actually survive ludicrous falls with minimal bone damage). Still, should no paralysis occur, your odds of recovery would be quite high in a wealthier nation. Modern medicine is quite honestly miraculous.
