Don’t want to go too far down this rabbit hole, but it’s definitely not 100% memorization. You have to know the words and which one to play. The “right” one to play is usually obvious, but on 2-4 turns per game, the strategy becomes very very very important. With perfect word knowledge and garbage strategy you could probably be around the 25-50th best human player and with a fair bit of luck, would win some big tournaments eventually.
