The 20-year-old Argentine marksman, who is on loan at Ewood Park until January, opened his account against Burnley at the weekend.
Di Santo made just eight league appearances off the bench in 18 months for Chelsea after joining from Audax Italiano.
However, he has been given the chance to start under Sam Allardyce and is enjoying the experience of first-team football.
Chelsea could recall him as cover for Didier Drogba during the Africa Cup of Nations but he is unlikely to play he would rather stay with Rovers.
"I need to improve and gain experience," Di Santo told the Daily Express. "I need to play games and score goals. If I got back to Chelsea I will try my best but, if I stay here, I will continue my education.
"It is good for me being at Blackburn. I am very happy to be here because the manager has given me the opportunity to play. That has given me the opportunity to improve and gain experience and I hope to get better and better over the next few games.
"Sam Allardyce is helping me to become a more complete player. I have the ambition to be able to play in every kind of style so, if I have any problems in certain areas, I want to work harder to fit in with that particular way.
"I hope to get back to Chelsea and play. If I go back and don't play, it is less good for me. It depends on the situation.
"One of the main reasons to stay here would be because of the supporters. They seem to love my name I think and that situation gives me more confidence to continue here.
"I feel I have proved I can play in the Premier League by coming here but I need to improve every game. I need more experience and now Blackburn have given me the opportunity to play more games."
Chelsea 1/5, Draw 5/1, Blackburn 14/1
