Usually Digital Twin = Model = Simulation. Different industries have different words for it. Some call a difference between a Digital Twin / Model and a Simulation where the simulation is the result of some external input being applied to a Digital Twin.

Either way I wouldn't think too much about it. Tech is full of these things. I have been working with AI and neural networks for years before it was called Machine Learning. Now I'm forced to use the term ML to sound relevant even though it is the same thing.
