In an ideal sense that’s true, but to use your analogy to make the opposite argument: consider someone that has no knowledge of what kinds of moves where made previously in this chess game and other historic chess games, even though theoretically they can figure out a good move given enough time to read the board but that is prohibitively infeasible. On the other hand it is people who have studied games of chess played in the past that end up building an intuition for what a good move is and are much more likely to come close to making a good move in a reasonable amount of time.
