Voice lessons will improve the sound you already have, but they won't guarantee you a singing voice worthy of fame. Everyone can learn to sing better, and a voice teacher can help you learn how to use your voice to the best of their ability. Of course, as a voice teacher, I think voice lessons are worth it for anyone who wants to improve their voice. Singing lessons are worthwhile because they give you the opportunity to improve your voice through training and practice.
With this in mind, singing is much more a skill than a talent. Sure, it takes a combination of talent and hard work to become the next Pavarotti or Adele, but anyone can improve their singing voice with hard work and practice. If you are a person who tries to sing well but always ends up missing the pitch, listening to someone without professional training do it effortlessly will play tricks with your mind. To me, it seems that those who know how to sing are born with it and voice lessons only improve your voice even better than it naturally is.
The important thing about the lessons is that if they are taught correctly, your teacher should know not only what sounds good and sounds more meh, but also what someone has to do to achieve a particular tone. If you get a vocal coach (a good one), he will teach you the proper technique for singing, as well as warm ups to help develop your voice. Ask anyone enrolled in singing lessons and they will tell you that their vocal performance changed dramatically before and after singing classes. That doesn't make pedagogues wrong per se; it's just an example of how, especially with singing, we try to convey the sensations you feel in words, and that's often inaccurate.

Breathing exercises are essential to learning how to use the diaphragm, which is crucial for developing a powerful singing voice. Movie stars learn to sing all the time for a role (usually surrounded by a team of vocal teachers and months of daily practice).
Even if you are not using an optimal technique, you will learn a lot about musicality and train your ear by practicing singing. A proper shape, or singing position, is essential to get the most out of your instrument, that is, your vocal cords. The truth is that there are very few before and after shots of teachers who say that singing lessons are necessary. In the meantime, breathing exercises will help you improve your lung capacity and use your diaphragm to sing, thus improving your singing resistance and the ability to mimic various levels of tone with precision.
