The ArtShop shows exactly how it is one, albeit with smaller number of records. 
It has 25 records and shows 9 records (art images) per page.  So there is a total of 3 pages. 

In your scenario, you have 1000 order records and if you show 50 per page, you will have 20 pages. 
The idea of pagination is to show data in maneagable pieces (i.e. pages). 

Hope this answers your question.
