"Individuals and interactions" is not saying "hire good people", although I can see why you could read it that way. I've always understood it to be saying, "Get people together in a room and talk and figure out what to do", instead of "rigidly follow an arbitrary process".
For example, let's say that we did some project planning a month back, which says that we should start on a certain new project tomorrow. Everyone on the team is grumbling and no longer feels like that's a wise expenditure of resources. What should we do? Stick to our goal and follow the process, or get people together, work it out, and set new goals? Agile is saying, especially when you consider other bullets like "Responding to change over following a plan", that people subscribing to the Agile Manifesto value getting individuals together, collaborating, and responding to change more than following their plan.
