Going by name alone, I have always assumed that insufficient material is a test for draw by insufficient mating material (i.e. two kings plus either a bishop, a knight, or two knights). Random play probably changes the seed value for the hash keys, different move ordering, or something to that effect, and results in different moves played where the evaluation is similar. Contempt is the draw avoidance parameter, i.e. an engine "pretends" that it is up by 1.5 pawns (by default) when it is doing searches, so that if it finds a draw by perpetual or a similar draw, it will not play that line unless it is actually down 1.5 pawns.
