I think it's a catch all term for something result driven. They manage bugs, products, do sales and marketing, remove legal obstacles, UI/UX, events, PR. Often just identifying what's preventing further growth and calling for company resources into that direction. Much of the sales on an app isn't marketing/sales at all - look at something like Fortnite. Part of it is community and UX, but the end goal is more money.
