How can geese be so intimidating to bigger animals? Would a human be able to do the same?

Question

It is pretty easy to find videos of geese standing their ground or even straight up attacking bigger animals, usually cows. Why does it work?

As far as I know, geese don’t have bright colors indicating venom, or big fangs, big talons, super lound cries. Where does this intimidation come from? Why do animals avoid them at all?

Would I, a human, be able to scare the sh*t out of a herd of cows by opening my arms and screaming at them too?

There’s a group somewhere in Africa that “hunts” by walking up to Lions and stealing their kills. They carry themselves with so much confidence that even lions don’t fuck with them. I could probably find the video but I’m sure it’s easy enough to find using Google.
