Yes and no. One could say this of any game with points where the margin of victory doesn't affect long-term outcomes (e.g. most ball games).
replyA win by 1/2 point or 20 points it suggests a very different relative skill between the two players. Similarly the custom of the stronger player playing white without komi suggests that the point differential matters.
Not necessarily.
In go you often calculate the score and come up with a conclusion that by playing proper moves you will lose by a small margin.
