"I'm not sure specifically but there's definitely parts of me in Rikku"

Tara Strong's quote suggests that she has an individual connection to the character Rikku, which she represents in the Final Fantasy X computer game series. This could imply that she has actually related to the character in some way, or that she has actually made use of her own experiences to bring Rikku to life. It could also indicate that she has taken a few of her own personality traits and integrated them into the character. Whatever the case, it is clear that Tara Strong has a strong connection to Rikku and has put a part of herself into the character. This might be why fans of the series have grown to enjoy Rikku so much, as they can see a part of Tara Strong in her. It is a testament to Tara Strong's talent as a starlet that she can bring a character to life in such a way that fans can connect to them on a personal level.
