Yes, still apply.
Don't overthink the personal statement, it's really not the most important part of your application. Medical schools have several thousand applications to sift through - they're looking at your GCSEs, A-levels (or equivalents), interview scores. They're not sat with three thousand personal statements printed out on a big conference table being like, 'well, X said they led scout camp, but Y mentored a year seven student'.
The main thing I would say about the personal statement is, just, don't mess it up. Check the spelling and the writing quality is at least okay - obvious errors might be a red flag. Check that it definitely reads as an application to medicine and doesn't sound like you're hedging your bets and maybe applying for biology too, that can be a red flag. Don't accidentally be racist (not even a joke).
Schools will tend to focus a lot on the personal statement because it's something they know how to advise on. The much more important thing I would suggest is that you start researching entry requirements as thoroughly as possible make sure you meet them exactly, and that you don't do anything that could make you ineligible. Most rejections are because candidates just narrowly missed some criteria, few are to do with personal statements.
