Yes, it takes several years for one to produce like that and it would more than likely grow very large. Also, probably not produce the same kind of apple that the seed came from.An apple that was too damaged to use at work because of mold and bruising. It's mainly just for fun, it wouldn't even be producing by the time I moved most likely. I'm just kinda messing around with growing things while I'm still at this house so I know what definitely won't work when I actually try growing a proper garden.
Nothing wrong with any of that. And, nothing wrong with just having fun.
