Certainly, about one year or more has passed since you first inquired about and named your desires, ambitions, and hopes on Y/A.
It is time to make a move - stop asking and start acting. In this past year(s?) you could have either found out your ambition does or does not measure up to the reality, or have been further along your way if it does.
Direct inquiry, locally, meeting with actual people, as suggested by Mamianka and all those before who similarly answered and know your geographic location, is the only way you will get any further real information or have any chance of your ambition becoming an actuality.
You've been given specific info on what and who sits in your immediate environs, and it is you only who can act upon that.
If I recall, you are past twenty and still live at home. If you stay at home you will ultimately look back and find you've had no life At All, pianism or music career aside.
Most careers are established between the age of twenty and thirty, meaning there has been (often for professional classical performance) fourteen to sixteen years intensive preparation and study prior the age of twenty.
To say 'you're late' is a massive understatement. If you are to move on this at all it must be immediate. Get direct answers from local experts, figure out how to proceed, and stop second-guessing by asking on line. Nothing will happen that way.
Pick up the telephone. Make appointments for interviews; be prepared to show them what you can play and how you play. Make more than two appointments / interviews, but not twenty - beacuse each will give you slightly different, though similar advice.
Best of luck, but you have to move on this, or you are heightening the probability of its being over before you have begun.
Concert performance training, apart from private lessons and a lot of ensemble performance classes (chamber music and accompanying) includes many necessary academics - music theory, solfege (ear training, sight-singing and dictation) and music history, the latter of which will include writing one or more research papers. These are all basic requirements for undergraduate diplomas as a music performance major: they are unavoidable if you wish to become a real musician, and if you wish a diploma.
Best regards.
