YES - you can teach yourself. But - NO, NOT 'stickers'!
I assume you can drive a car? You don't need 'stickers' to show you which pedal to use, or which gear you are in. Kinesthetic or muscle memory lets you know where you are; similarly with piano or keyboard, provided your Right Hand thumb knows where middle C is, you can work it out from there.
You don't even HAVE to think about the NAME of the note on the keyboard, but if you are reading music the brain/hand should go straight from the note on the line or in the space, to its position on the keyboard. If you have to 'translate' into the name of the note as well, that is another step the brain has to make, which is unnecessary.
I assume you DO mean proper piano ('real' or digital), like Lang Lang; and not keyboard, where the 'automatics' will do the accompaniment for you, while you concentrate on the melody.
I taught myself to play electronic organ, with two manuals and 13 note pedals, with reasonable success, but I already played drums in semi-pro bands, and knew a certain amount about music.
But one thing I DIDN'T realize for a long time - and this is important to make learning and understanding easier - is that middle C in written notation, is on the ledger line BELOW the stave in Treble Clef, and is the same note that is written on one ledger line ABOVE the stave in Bass Clef.
For years I struggled, thinking Treble and Bass Clef were two different entities, when in fact each is a continuation of the other. This is known as the Grand Stave (or Staff) and is HERE .
Another thing that is very useful to 'get you head round' if you can manage it is: Why is there no Black note between E & F, nor between B & C? (I will leave you to work/find out the reason; PM me if you can't.)
Yes, the John Thompson books are good and I used them for a while. Also good for adults are all the Kenneth Baker piano books, and he also has series for organ and keyboard.
When I was trying to improve my Bass Clef playing, I tried some simple Mozart pieces, working out the Right and Left hands separately. I was surprised to discover that there was just as much good melody in the Left Hand part as in the Right, and it wasn't just an accompaniment.
When I was a primary school TA, I taught recorder, and a bit of keyboard. Children always had difficulty remembering Chords. If one understands where Chords 'come from' it makes it easier to work out or remember them; in due course if you need to know that I'll tell you a bit about it.
If, however, you already know most of this stuff, I apologise for going into so much detail.
GOOD LUCK and Enjoy!
