I'm just a senior IC, and not at FAANG. But my employer does recruit from FAANG. 0%-20% sounds low for dev work, but the basic description looks somewhat familiar. We don't have project managers, and not all teams have product managers, so seniority can get you more of that work, and less dev work. I don't think ICs do managerial people management if you don't include mentoring. And I do know one or two directors who still code a lot. Maybe some FAANGS have senior positions with more IC dev work.

They do, but it's vastly easier to get promoted to those levels as a manager, because the organization needs managers to function, but super senior ICs are less critical.
