Whether you configure DataLoader to use Bulk or SOAP API, the records will insert in batches of at most 200 on the salesforce side. This is to avoid hitting Governor Limits. With this in mind if you are to insert 1000 records you must consider 5 batches of 200. This means the trigger will fire 5 times.
