I have had classical training all my life. But, I know I do not come close to any of these singers. Expecially not Vinit. He is naturally talented and a lot of great singers were. Mozart played the piano at age 5. Vinit begin the guitar on his own without any lessons and started singing at age 5. Sonu also started singing at a young age. Riaz and training will obiously be good for him and will make him better than he is. I agree with that.
What he needs work on is his immaturity. I agree that he is 17, but someone needs to teach him the art of diplomacy. He is obviously not learning it from HR. This is very poor behavior. I am disappointed in his talk being a Vinit fan myself. I know his young but he needs some humility!
