Sort of. If you can touch type you can learn to play the piano. It's all the same thing: muscle memory.
I bought a digital piano a few years ago and just sat down and played the thing. You don't need headphones - just turn it down a bit.
Because it was a new toy I was obsessed with it and played several times a day, getting better each day, and trying new things like octaves, minor inversions and arpeggios up and down the keyboard until I was good at them. To non-pianists I sound like I can really play, but really I know I'm not that good. My left hand is dreadfully limited.
You can go a long way just playing what you want, but you need to get the basics right first, and if you want to play classical then doing it "properly" is almost certainly more important than for other styles of music. You can probably learn everything off YouTube these days. That's how I'm learning drums.
How hard is it to learn the piano? Am imagining an electronic keyboard with headphones so I don't annoy the neighbours. I had lessons when I was 8 but didn't get far because I disliked the teacher and never did any of the practice sessions I was meant to. I would like to play classical stuff, not just the plinky plunk things you have to do when you're learning.
