I call it 50% "luck" and 50% skill.

However, I define "luck" as the cards that are dealt. You have absolutely no control over them. Skill is how you play with the cards that you are dealt.

There are some other good comments in this thread though.

How you play should be 100% skill just as the cards that you get are going to be 100% "luck".

Since skill can be improved that is what should be concentrated on.
