One of the things that's unique about MOBAs compared to first person shooters is that killing opponents doesn't necessarily translate into winning the game. It's a little more more complicated than this, but for the sake of simplification, the victory conditions in MOBAs are more like capture the flag. The goal of the game is to destroy the enemy's nexus, in the center of their base. Killing enemies makes it easier to take objectives and eventually the nexus, but strategic gameplay can also do the same thing. One of the primary differences between high level players and beginners are decisions on when to fight. Beginners love to try to get kills, so they run around the map chasing enemies. This can get them short-term enjoyment, but is usually a poor strategic decision. Experienced players will concentrate more on acquiring resources and taking objectives, only fighting when it's strategic to do so. Since beginners are fighting all the time (and are less skilled), they'll end up having less resources and objectives than experienced players as the game progresses, snowballing the experienced players to victory. While there's an element of mechanical skill involved in the fighting highlight reels (like the one you posted), there's an equal element of skill involved in getting a resource lead on your opponents so that your character is more powerful than theirs. Once you have that lead, fighting and securing victory is much easier. Conversely, if your character is weaker than your opponent's, it's usually a good idea to avoid fighting them until you can secure resources or objectives to even the odds.
