There are actually 3 lists if you count the Wordlebot 2.0 [1] list:
1. The words that are solutions in the current game
2. An approximately 2x size list that is the space Wordlebot uses to "play" in. Supposedly it's still common words though some seem pretty weird to even a native English speaker (and some British slang leaks through as well). For example, titer was one of Wordlebot's recommended guesses today which I correctly sort of assumed had something to do with titration but would probably never have guessed it.
3. A larger pool of words that Wordle will let you enter as guesses
