ELI5: If collagen is a protein that is broken in the stomach into amino acids, what is the difference between having collagen or any other source of protein like whey protein?

I found a BMJ study in snakes that suggests collagen is broken down enough by stomach enzymes to be absorbed.

Collagen is predominantly rich in only two amino acids though, so it would be better to have a protein source rich in as many essential amino acids as you can.
