This is a situation, Lee, where the phrase could mean either thing - the plain definition or a play on words. A plain or straight reading of the phrase would indicate a cook or chef, but if the speaker was trying to be clever or play with the language, it could also mean food. It depends on the context and tone.

Hello Lee, “Not anyone can be a great cook, but a great cook can come from anyone." The second ''great cook'' means a chef as well.
