I would say in most videogames you can play against the computer (Age of Empires, Call of Duty, etc.), which use human-set rules without machine learning. Computer enemies show the same behavior, regardless of your specific knowledge of the game. I think nowadays there may already be some games where the computer learns from your behavior by machine learning, but this is not the norm.

There were also chatbots before ChatGPT existed, which in their most basic form give human programmed answers to specific questions.
