> Surprised that a 13 years old was able to take care of 3 small children in a jungle full of snakes and jaguars for 40 days

FTA: "The children belong to the Huitoto indigenous group."

I.e. they're used to living on the land. Snakes are a concern if you're unwary in the jungle, but if you are somewhat aware of your surroundings you'll be OK. Jaguars are probably a different story, but I guess luckily they weren't in the territory of any animals.
