As with many things in life, see it like stats in an RPG: your 'character' may have "0" in the singing skill INITIALLY. But it's still a skill that you can learn, even if you start low.

However, what is true is that, you will sound like YOU. You can get close or make impressions of artists you like. But ultimately your voice is YOUR instrument and it can gain range, and power, but you'll sound like you.

For instance, I'm well aware that I will never have "Celine Dion's voice". I don't mean her skills, I mean literally her voice.

That's what one of the first AND biggest tough thing to accept when singing: you might never sound exactly like the singers you admire. But it doesn't mean you can't sing or be extremely good at it.

It's like Michael Jackson was sad because he knew he would never be able to sing like Barry White. Does that mean Michael Jackson is not a good singer? Nope.
