The quotes the OP has aren't usually said when it's a sales discussion, for e.g. "PS3 outsold Wii again", "Xbox dominated 08 holiday", etc. Those are undeniable objective facts, and they do "matter".
These quotes do come up when well reputed and attention grabbing fanboys make threads bashing another console over an subjective opinion such as "Gaystation 3 sucks" "M$ is evil", etc. These kinds of threads sometimes do bring up objective, but irrelevant facts such as sales to support those subjective thoughts. It's not that "sales don't matter", but it's that "sales don't matter in how good, fun, and enjoyable a console is".
