The actress made her debut last year in Dabanng opposite Salman Khan.
She told New Kerala: "I think everybody here has something to offer. Everyone has their own charm and their own personality.
"Everybody brings something new and something different for the audience. I don't believe in competition."
The 24-year-old added: "It's just being at the right place at the right time.
"I am happy that I am working with some of the best and I consider myself very fortunate enough to have got such a chance."
In May, Sinha was forced to say that there was no truth in stories of rivalry between her and leading stars such Katrina Kaif and Zarine Khan.
The star admitted recently that she did not want to be in the movies before being mentored by Salman Khan.
