An uninvolved person is anyone not taking part in what you are doing. Passers-by, neighbours, people in gardens, people in cars, on trains, on boats, and people inside buildings all count as uninvolved, and the separation distance rules protect all of them.
Involved people are the ones with you and part of the flight: your client on a survey, a colleague spotting for you, a friend helping out. They have to actually understand what is happening and accept it, which means you have briefed them. Simply standing near you does not make somebody involved.
The distinction matters because your minimum separation distances apply to uninvolved people, not to involved ones. Get too close, and you are flying illegally, so the safer instinct is to treat anyone you have not personally briefed as uninvolved.
