the understanding has a basis in 'alive' and 'dead' as like robots are dead and so is kind of trying to claim gameplay is interacting with a robot as inherently inhuman
Doesn't seem like a particularly well thought out initial stand from the OP, wherever they are. It's hard to argue against someone who isn't even here, but I'll give it a bash.
Playing with toys and solo games are absolutely gameplay. It's how game developers get a finished product - they play it out running one or more players themselves to see how the game functions. As children we play by ourselves at times. As adults we frequently play by ourselves (only it's the adult games on our phones as we're going to work, or of an evening on our computers). Some of our oldest artefacts are of toys made tens of thousands of years ago and buried as grave goods with beloved children when they died, and children play with toys to the present day, alone or in groups. The idea that "gameplay" cannot exist with one person and an inanimate object is nonsensical.

I strongly recommend separating your stranded thoughts out into paragraphs for easier reading and comprehension by the reader. When I was a student one of my teachers said, "The purpose of communication is to be understood," and the fewer barriers we place between our message and the recipient the better.
