A sport is something you do for fun ( synonymously, 'for sport' ), regardless whether it is physically demanding. A toy is something you play with, regardless of the complexity or skill involved. A competition is a event in which you are measured against another person or other people. These things aren't exclusive of each other, so we use some of these words interchangeably sometimes. I try not to worry about what other people call my stuff, especially since there is so much ambiguity. My 2 cents.
