"The first book that they gave me was Jeannie, a young teenager. I went on with her maybe ten books"

This quote is likely describing Dan DeCarlo's experience as a comic book artist. Jeannie was most likely the very first character he was asked to draw for a comics series. He was likely offered a script and asked to draw the characters and scenes as explained. He was most likely so effective with the very first book that he was asked to draw the next 10 books in the series. This quote is likely a testimony to DeCarlo's skill as an artist and his capability to bring characters to life through his artwork. It also speaks to the trust that the comic book publisher had in DeCarlo's ability to develop a successful series.
