The article is sourced from The Information, which says "Google plans to reorganize a big part of its 30,000-person ad sales unit, an executive told some staff last week, prompting anxiety that some departments will face job cuts."

That sounds like a exec said there would be a reorganization of a "big part" of a unit of 30,000 people total, and people are worried it will include some layoffs, which is not the same thing.
