I don't think there are any commercial-grade hardware gaming aids on the market right now. If we don't count gaming keyboards and mouses with macro functionality (some folks consider those "cheats")
All the devices I've seen were hobbyist DIY proof-of-concept hardware. And if we're talking about real hardware assist (a machine that sees a screen and helps human operator with their inputs), it needs a machine vision trained for a specific game/setup and that's also quite an effort.
If there are out-of-the-box options now, then yeah, it could be as you describe.
If you're assuming everyone knows how to wire up motors to a microcontroller and get the software set up and calibrated, that's not accurate. If you want to minimize that to a term besides "skills," that's your prerogative.
