Right, they ship cars to delivery centers to match current demand. Most cars do not sit in inventory very long, they are already spoken for by orders.
This is especially true in countries where the cars are delivered by container ship. You can easily make headlines about "Tesla has record sales in <month>" and "Tesla has poor sales in <month>" based on which months the ships arrive and the cars are delivered to customers.
I'm not sure what about this indicates that they don't have inventory control.
