I'd say that's stretching the definition of social beyond the breaking point. Technically those interactions involve other humans, but none that you engage with directly. It's direct human interaction that is the key to whether something is 'social' or not IMO.

Quite the opposite. Yuval Harari explains really well in Sapiens that one of the keys to human success has been the ability to "do things together" at larger scales than any other species. For example, maritime trade going back millenia. That is true social "trust" in each other. The whole concept of money being a social construct is a very interesting thing to consider.

> "Quite the opposite."

Consider the context. The subject under discussion is those who want to be alone. It's quite possible to be alone whilst still enjoying the fruits of human collaboration.

I believe that was the point that your parent was trying to make; clarify that "Humans are social creatures" doesn't mean that all of us love interacting with people, but that the quote implies that we can come together to do things in a way that others cannot.

What animals also do this ?

Bees, ants, and other social insects have complex societies with division of labor. One difference is that in insects, the roles are probably more hard-wired and instinctual while in humans these roles are more malleable and depend on culture.
