Victories are created by being good (or lucky). Such a team is going to have more wins that other results, and so it will it is likely to have better results in one-goal games - more wins than losses or draws.
A team that is strong on defense is going to have more one-goal games than a team that is weak on defense. Lower scoring games are going to lead to closer results.
