Do I need to pay customs for my personal belongings sent from France? How can I avoid it?

Hi, fellas, I need some help. I read the article on https://www.toll.no/, but it states that I have to live there for at least a year to move my belongings. The old man I was staying with sent me my suitcase with my clothes, my hair/skin care products, and one board game. There are no tobacco/alcohol or stuff like that which people usually buy for cheap abroad. And all the hair|skin care products are not new but partly used, so it is not a "harryhandel".
Do I need to do anything at all? On the package, it is specified that those are my personal belongings, but for the insurance I stated the value of the things inside to be rather high. Will they force me to pay import tax?
