Wrong. Sasuke received training from his clan at a young age (his fire jutsu). His father told him all uchiha are taught that jutsu at a young age. Itachi told sasuke to go to the secert hideout to learn about the sharingan's true power and to read the stone tablet that has been handed down throughout the ages. What I am saying is at some point in their lifes they were given training and knowledge about their clan. Naruto didn't know who his parents were until he was 16 and has never received any type of training or knowledge about his clan even thought there is an Uzumaki shire at the edge of the village.
If it's to talk about the entire life, Naruto also got advice from family.
Kushina help him to defeating the fox and told him about the past.
Minato gave him a special seal so he will be able to use the fox's chakra.
Nagato give him advice and told him about his past and true peace.
Naruto also learn shadow clones, technique made by a Senju, who is related to him.
Jiraiya was also considered family since he chosen him name, so him teaching rassnegan was part of the family.
Minato also left jutsu for Naruto, rassengan.
