Yeah, games are so misunderstood. It's not just for kids, and it's not just entertainment, it just happens to be that way because of the stigma. They are interactive experiences with software and that could be virtually anything. The learning and training potential is huge if companies started making proper games again (where the experience is priority) and not fancy theme park pay2win casinos for children.
Games are just rich interactive models of some synthetic, emulated, or simulated system. They can be perfect for building intuition about complex systems that are difficult to represent linearly as in text or video. Games could be a very promising future for education & training but they still carry an old stigma with them & the f2p ad driven game wasteland of the app store only helps reinforce that stigma.
