If there are people who want a serious answer from me, then here it is. There are parts 3 of the triforce, Power, Wisdom, and Courage. When Ganon touched the Triforce, he got power because he was the first person to touch it and it fitted his personality. Link got the ToC because he is the hero. He risks his life to save Hyrule, so it makes sense. With Zelda it makes sense for her to have it. She is very wise for her age. She knew that Ganondorf was trying to get the triforce, she knew the six warping songs, ect. She seems to have powers because she has visions of prophecy, summon the light arrows from where ever, ect. The Deku Tree calls her "The Princess of Destiny" because its her destiny to be a sage, help Link learn the warping songs, help Link fight Ganon and its her destiny to lead Hyrule into prosperity, so it makes a lot of sense for her to have the ToW.
