Should I have more musical experience?

It’s been my lifelong undying dream to become a successful musician. I’m 17 and look up to various artists (Queen, Bowie, Harry Styles, etc). It would fulfil all my life dreams to follow in their footsteps, however, they seemed to be more musically experienced than me. For example, Freddie Mercury was in and out of bands and learned to play piano very, very young before he rose to fame, Bowie played various instruments. I’m planning on starting piano later in the year and taking up singing lessons. I take music as a subject in school. I feel I’ll never be successful because majority of my icons were more heavily influenced by music when they were young or came from a musical background. I get panicked as I feel it’s too late for me to ever succeed. I hope to study music in university but not sure if I’m good enough. I’m not sure if I’m looking to deep into it, I just notice a pattern in all my inspirations musical journeys and it’s always that they started extremely young. It worries me loads. Should I be worried? Should I compare myself to them or should I focus solely on my journey? Is it too late for me to fulfil my biggest ambitions?
