Yes! Sure, some individuals may start out with more natural ability than others, but singing is a skill like anything else. No one is born with the perfect voice or vocal techniques, and even naturally skilled singers need a guide to improve their vocal skills through training.
Just like with anything else, becoming a good singer takes time, patience, and effort. The best way to improve your singing voice is to take lessons from a professional vocal coach who can help you develop proper technique. With the right guidance, anyone can learn to sing well.
