No, a competition but not a sport
All sports are competitions, but not all competitions are sports. Dancing can be a competition. It certainly involves physical movement, but so does darts, bowling, etc. They involve moving and point scoring, but can they be called sports? No. In a competition there is a goal or action that is scored, scores are compared between competitors, but there is no direct physical interaction between competitors that could be described as offense and defense. There would certainly be some competitions that fall into a gray area between competition and sport. Some racing events are largely without offense and defense except perhaps at key moments like along turns, and coasting behind the lead runner or lead car. But things like soccer, baseball, football, tennis, etc that contain offensive and defensive aspects fall into what I consider sports.
