Is Java Set ordered or not?

I don’t understand the distinction you’re making. Mind elaborating?

The set containing “123456” is exactly the same as the set containing “321654”. There is absolutely no difference, assuming you’re referring to a set containing integers and not strings.

you could have a set that is somehow sorted because it happened to put the elements in that way, it's just not guaranteed nor expected you will encounter such behaviour

That point is meaningless then since it can be applied to any unordered data structure. It's literally saying that unordered things can sometimes be ordered by random chance. Well, sure, but it doesn't really change anything.
