AI is a pretty broad term - its been used for generations to mean something intelligent seeming that isn't human. Certainly, computers running precompiled instructions also falls in that category.
Those are definitely exaggerations for marketing purposes.
I find it incredibly silly that 20+ years after the first more advanced "AIs" in games like Half Life, we're still far from a point where I can fire up a game of Dota 2 with bots and have the bots behave constantly well at an intermediate level, so that I can turn Dota 2 into a solid single player experience (I don't have the time nor the patience, anymore, for managing a team of toddler brains for 30-60 minutes).
Yeah, I wouldn't classify mechatronics or bipedal locomotion as AI. It gets blurry when considering algorithms in control systems, but I wouldn't classify those as modern AI/ML systems.
Nobody reasonable considers ifs and dependency injection to be AI.
