No. The answer is in the question giving away a book is NOT a sale. To be a bestSELLER you have to sell a lot of books. To call yourself a (recognisable) bestseller like USA/NYT, there are sales minimums of between 4,000 and 10,000 PAID units within one week.
We discussed this in another thread, and to interest an agent I heard you need a minimum of 10,000 sales at a price point of $2.99 or higher. Michael stated that due to the flood of free/cheap books the sale point may be higher now and more like $3.99.
