UserInDB(**user_dict)
```

would be equivalent to:

```Python
UserInDB(**user_in.model_dump())
```

...because `user_in.model_dump()` is a `dict`, and then we make Python "unpack" it by passing it to `UserInDB` prefixed with `**`.

So, we get a Pydantic model from the data in another Pydantic model.
