Agreed, the title is misleading. But you're also misleading by saying that these are merely some 130K out of millions of titles.
Those are 130K of the highest-selling books by volume on Amazon - I wouldn't be surprised if they accounted for 30-50% of sales, even though they're a much smaller fraction of the millions of titles
So it's not 12% of Amazon sales, but still a significant fraction of that.
