Crocodiles are savage by nature, so why don't they eat hippos? Is it because they can't win?

The video content is as follows:

Crocodiles are found to be one of the earliest and most primitive reptiles alive to this day, and they are also fierce-tempered carnivores that lived alongside the dinosaurs. Besides their thick scaly hides and heavy long tails, their conical teeth are also their most advantageous weapon for attacking. The bite force of an ordinary crocodile is about 990 kg, and the bite force of the most formidable saltwater crocodile is about 1900 kg! Yet the bite force of an adult man is only around 46 kg! A crocodile's bite force is dozens of times that of a human, so if you fall into a crocodile's jaws, what hope of escape is there!

But why does such a fierce, carnivorous crocodile not eat hippos? Is it because it can't win? In fact, it really is true that crocodiles “can't win” against hippos. The crocodile's hide is thick, but the hippo's hide is even thicker; a hippo's hide is about 50 mm thick and very smooth, and a hippo's body is far more massive than a crocodile's. Most importantly, a hippo's bite force can reach 2200 kg! Biting a crocodile to death is no problem at all, right.

So it's not that crocodiles don't eat hippos, it's that hippos are too strong in combat, and with their thick hides and huge bodies, there's no way to get a bite in!
