No. In Backgammon there is skill and luck. One can win games with luck and no skill or with skill and no luck or having both luck and skill.
You say that someone must have luck to outplay another. This is not true. He can do this if he has the ability/knowledge/skill even without much luck.

What i meant was that the quality of moves i played was much better than my opponents, but the luck they had was enough for them to win me. Despite the fact that i was playing the best moves while they played wrong, the dice for them was MUCH better.
As i've said my pipcount number of my first ~60 games was 86% of the pipcount number of my opponents. That was VERY strange. Now after 120+ games, i calculated it again and it is 96% of my opponent. A logical value.
