Figuring it out on your own is science, but I have a feeling OP didn’t actually personally search the world for one-horned horses or pointy eared-people with long lifespans. I bet they didn’t even work out how biology changes with scale and how evolution works to show that there can’t be tiny winged people.
Simply containing each number sequence is a significantly weaker property than having them all occur at the right frequency. Still, while nobody has proven it, it’s generally expected to be true.
