No, that's PR. Marketing is buying ads, buying reviews, buying people.

You're correct, but also I think we can assume this is referring to classical marketing, not all merketing.

There's a few separate threads of people responding to your comment regarding what marketing is, so it's probably helpful to add what the guy actually said in the linked article (I know, who reads the article anymore🙄).

"Marketing is dead," he said. "Marketing is dead. It truly is—I can back this shit up, man. There's no channels anymore—it doesn't work. You used to have marketing, communication, and PR. Marketing was essentially a retail theory—you were trying to get your box on the right point of the store shelf, and you have partnerships with retail stores. Those pipelines are gone. Now you've got the internet. Nobody is looking at ads anymore … all of the channels that we would usually market through are no longer really viable. So their function is also reduced by the fact that players just want to be spoken to. They don't want to be bamboozled—they just want to know what you're making and why you're making it and who it's for."

The main difference I think has to do with how this is done. Marketing is much more aggressive. Think like Google ads where products appear in unrelated queries. Much more sensationalism and less information. While the article says gamers want to read actual reviews, comment on the game while being developed, etc.
