Of course it is possible. Just put enough of work and dedication into it, and you will be able to play those concerts yourself.
It is frequent topic, this, and it always ends with "naaah, you cannot become the next Kissin, unless you did not start as a progidy at the age of 3 and made your concert debut at 11" and yada yada, thus keeping the old myth alive that this profession is not for mortal people and that "old people" (do you REALLY consider yourself as such?) cannot learn because their brains have stiffened and blahahahbabla.
Truth is, that you really don't have to be "the next Kissin" in order to play a piano concert.
Truth is also, that if you want to belong to the top elite division of concert pianist stars in the world, you will have to compete with literally millions of aspiring concert pianists in order to belong to the top 50 league.
Truth is also, that you can find a lot of opportunities to play, solo and with orchestra, even if you are far below this elite division. There are some piano concerts that are infamous for being very difficult, but there are also many that are quite possible to play even before you have got grade 8+++ or whatever ...
Piano playing is, especially in my home country (Sweden) infected with a terrible elitist thinking: either you must be a hyper super mega talented pro (and start practicing before you get out of your dipers) in order to "become a pianist", or you have to just forget the whole thing. Actually it is something most people can learn to do, just as most people can learn to sing decently. However, most people don't become a new Celine Dion.
So: do you want to learn to play those piano concerts? Yes, go ahead! Have fun!
Do you want to become world famous? Well - nothing is ever impossible, but then you need to invest a lot more than your "free time". You have to dedicate your life to this, and there are no guarantees that you will make it.
