Digital distribution sales are normally never presented as a unit of sale because there is no physical object being sold so realistically the game did sell over what was reported in the financial statement. Its just considered a different form revenue.
Remember Valve reported on sales of Half Life 2. They said there were something like 5 million retail units sold but after factoring in Steam sales it came to about 7 million.
