No they do not. In 2000 they served 20 million customer with a $2.76 Billion in sales (according to their 2000 annual report).
In 2012 they were selling an average of 3.5 million products per day. And of course quantity of customers is not quantity of products sold, as people buy more than one product (if they didn't, you'd be claiming the entire 7 billion world population was buying slightly more than one item from Amazon every year). Average product price is now $47 according to that link.
And of course they were almost exclusively books in 2000, but are very diverse in sales now. Book sales are not that different in 2014 than they were in 2000 for Amazon (they are different, but not nearly by the factors you're trying to imply). Amazon made $5.25B in book sales in the past year (according to Forbes). Compare that to their $2.76B in 2000 which was almost entirely from books, and you will see we are not talking about the kinds of exponential growth in book sales that you seem to think. And when you count only non-electronic books (PHB was not available in electronic version in 2000 or now) the differences become even smaller (20% of that current book sales number is kindle books). The year 2000 was a good year for Amazon book sales, and it was not nearly so different than now in terms of books.
I appreciate you want to know more about Amazon sales in 2000 versus now, as this is the third conversation we've had about this. But it's also the third time you've made clearly false statements about this topic, which could have easily been looked up. Amazon has grown a lot since 2000, but it's not nearly as much as you seem to think it is.
