The current world champion Magnus Carlsen needed around 15 years to go from beginner to world champion. He was probably one of the fastest ever because he started to play quite late (at the age of eight) and was the second youngest classical world champion (if I remember correctly).
He received professional training from a strong GM almost from the beginning. He played tournaments almost constantly. His parents took a year off work, to accompany him to tournaments. Due to his tight tournament schedule he didn't finish school, although it was a special sports school, where he received more chess training.
So, if you are 8 years old or younger, and you can afford to concentrate on chess for the next 10 years, you do have a shot at being world class some day.
Otherwise, not so much …
Anyway, I would advise you to go to a local chess club. Google tells me that there are chess clubs in Pondicherry. There you will find out, whether playing tournament chess is actually enjoyable for you. I believe that was a necessary step for every chess world champion.
