What analysts didn't factor in for this fight was the fact that the arena was flooded partway, 3 feet deep. This prevented the rhino from being able to charge at the hippo. That greatly leveled the playing field, pitting the rhino's horn against the Hippo's teeth.
It was a close battle and the hippo suffered many deep horn injuries from the rhino, but ultimately the hippo's melee game was simply stronger and the rhino lost mainly because it couldn't charge.
