Tuerto there is no ceiling but this is a difficult subject - I play the keyboard and did all my formal learning when I was a teenager, getting to Grade V but after that played in a band and that was where I learned a lot more about playing. I am absolutely no expert and there are ways you can learn to play something which sounds good without being technically good at all. Then I more or less gave up playing for years.
However, during this Pandemic I bought an new Yamaha piano and I am relearning - I love it and play (very imperfectly) every day now. All sorts. But the reason that this is a difficult subject is that what might simple to me and the other poster who played in a band would probably seem impenetrable to a complete beginner.
But I do think that You Tube is your friend in this these days, and there are all sorts of lessons for beginners which with a little bit of effort could help you advance quickly to a place where you would enjoy playing and really want to keep it up. No instrument is easy just to pick up and play, but if you really want to do it you can. The good thing about a keyboard is that sounds more complete than say guitar or most other instruments. And even fairly basic electric keyboards have functions which really assist the learner.
Good luck, it's a great ambition.
