Earlier quoted context omitted.
This is for Project Management, but I think OP is a Product Manager...
whats the difference?
Traditional enterprises and software consultancies tend to be organized around projects rather than user-centric products and their features, so they will more often have project managers instead. The product responsibility in turn tends to become more ad hoc, sometimes with someone assigned as a “product owner” outside their regular title.
(My personal view: if a company has project managers and product owners, that’s a sign that it’s probably not the place for me.)
