It’s this. There are many five letter words that are not “wordley”. Words such as, idk, bokeh, are technically part of the lexicon but would never appear as a solution. The wordle bot will even tell you this if you guess them — “good guess, but unlikely to appear as a solution”. The crossword has a similar sort of unwritten rule, maybe not as strict, but really hard technical words seldom appear.
