Every Link isn't the same link. Some of them are due to direct-sequel-itis, like MM-Link, PHand ST-Link and LA/OoA/OoS Link. OoT, TP (to some extent), WW, ALttP and LoZ were "Link gets sword without prior training and goes out killing".
actually, only OoT, if I remember correctly. THere he was just another Kokiri, any other time he was either son in a military family, trained since he was little, or had a job that required him to learn how to fight
Spirit Tracks goes on the Sword without training list, He was an engineer. Also sequence breaking because he didn't have the sword until he needed to go through the cave to the tower.
