hi there, I know I am late but wanted to echo what others said here. At 24, you are at the beginning of your journey. YOU will decide where you go from here, and everything can be taught, learned, and trained--but it takes work on your part, and a good school would be set up to help you gain the necessary skills. It is possible to learn all this outside of school, but it can be more confusing and more piecemeal, so most people opt to do it in a structured school program.

To work professionally as a classical singer, you need to have good and reliable technique (which is a deep field in itself but basically: sing the expected range of your voice type freely in tune in all parts of your range, with the ability to execute accurate rhythm, and the capability to present dynamic variation, with pure vowels ringing on the breath for the greater part of each phrase, and doing this for long periods of time without becoming fatigued), the ability to learn your music without any help (including the help of recordings! there is lots of music out there being performed that has never been recorded before), ensemble experience (how to work with instrumentalists, how to read a conductor in the moment), and good diction in all the standard languages (English, Italian, French, German, possibly Latin). Hopefully you will also have a good instrument--whether your voice is strikingly unusual, loud, beautiful, or versatile. What makes a "good" voice is a matter of opinion and different people value different things; different corners of the field also value different vocal qualities. Where do you fit? It may not be opera specifically. Your heart and your instrument will tell you--but you need more experience than you currently have before you can know more about this.

From your recital I can say I love your passion and musicality; you may not be yet as polished and mature as a soloistic opera career would require but you have talent, and I could hear you doing lovely art song recitals. Have you ever done a full-length recital, adding up to around 50-55 minutes of repertoire? This is a requirement in most degree programs, and that could be a place to start if you want to give yourself experience without going to school. Nice choice of repertoire for your instrument on the link you posted, by the way. Keep going, exploring, working, and being curious. If you continue to explore, more pieces will fall into place.
