There you go twisting shit again. Some of them call luck variance (I use both terms). The guys who have been APing for years who are in the black will tell you it's not by luck they are winning, its due to the math and skill.
If you have a big enough advantage on something, you can be certain it's not luck, its just simple math. For example: If you played 100 table game match plays over the course of a few years it would be almost imposable to lose given a simple basic strategy. That's not luck.
If someone is winning because they get a bunch of multi line dealt royals, I would say they were lucky.
