Using a simple example, I'm going to show you that skills are very important in poker. You can have Pocket Aces and win without showdown, or you can bluff and hold weak cards and at the same time force other players to fold their cards. Thus, in the first case, no skills are required, but for the second case, they cannot be dispensed with. So in the first case, it's luck, but in the second case, you can't do without skills.
