Hey and welcome.
I am very much like you in the sense I wish I had started playing trumpet earlier rather than having played guitar/piano, and none of which was 'serious'. I am 31 next month. I started around 28, and that also was not 'serious', but more or less self taught with which I had to correct some problems (embouchure understanding, breathing, support, etc - fundamentals) once I got a teacher.
Having said that though, already playing up to top line F after 2 weeks of solid practice and correct instruction from a teacher in person that can see what you may be doing wrong (if they are technically knowledgeable - good teacher is a must!).
I plan to be professional over the next 4 years. We are working through grade 3 already, he believes I may even be able to get grade 4 done this year. We see how that goes!
Either way, you being 23, by 30 (which is where I am starting from) you could be extremely good, if you have the right teacher and practice routine.
Also if I may suggest, do it to be professional. I find with myself, in past anyways, I never played instruments from the "lets be pro" perspective. Because of that, I never really practiced it either because I wasn't working towards anything. Sure I can play the instruments I played, nicely, but its nothing technically advanced and its not 'perfect' either. It more or less limited me to what I could have been. Now I am doing it from the perspective of being professional and I can myself feel the difference from how it used to be. So playing to be professional, even if you don't go there, would at least give you right practice routines to really progress. One thing I learned was, if you are serious about music, do your grades, they will prove how serious you are. Hence I started them this year and I already feel 'wow, I am really improving' as I am doing it much more serious than laid back because of the goal I am trying to achieve.
In regards to the mute - I had a normal 30 dollar practice mute when I was in an apartment. I can tell you it is not as loud as a TV. You can play the trumpet with a mute in your bedroom, and nobody will hear it in the next room of your own apartment, let alone the next apartment. It will also produce resistance though, harder to blow through, which can be good in the sense of strengthening your support. Then when you take mute off, BAM how much power you will have to the sound because there wont be that resistance anymore.
