Skill is more reliable than Luck
A line i heard before is something to the effect of
" in competition, when two opponents are are of equal skill, then luck is all that matters"
Thus luck more of a product of extreme skill. You are more likely to take advantage of such luck if you are skilled enough.
You can improve your skill but you can’t improve your luck.
Luck in itself is you relying into something you don't understand and that doesn't depend on you.
