Carl Sagan meant that all the chemical elements in our solar system were formed within stars, and most of them through the process of stellar nucleosynthesis, particularly in stars that went supernova. The explosion of these stars scattered the newly formed elements throughout the galaxy, from which planets like Earth eventually formed. Therefore, every atom in our bodies and every element on Earth was originally formed inside stars.
