The only way to own a copy of Wii Sports (not secondhand, that doesn't count towards total sales numbers) was to buy a Wii, which Wii Sports came packed in at no additional cost. It was a free game and was only available as a free game (you couldn't go to Walmart and buy a copy of just the game).
Nobody has a problem saying it's one of the best selling games of all time. If a free game can be considered one of the best selling all time, then a free download should as well.
Hell, Rocket League got its numbers because it was a free download and Psyonix is all the more better for it
