It depends a great deal on the game, but in many (perhaps most) cases, the AI simply cheats, or gets an invisible penalty for “easy” bots.
In Civilization VI, for example, the highest-difficulty AI settings start with several extra settlers, giving them an enormous head start. I think they may also get bonuses to various yields, meaning they simply produce *more* resources than an equivalent player would, even if nothing else changed.
Making a truly “intelligent” bot is *very, VERY* hard, and even the advent of modern machine learning techniques does not necessarily make this task any easier.
