Ok when im trying to buy Elf primary gradient i get this error

You do not have enough qi to buy Elf Primary Gradient. You have 1533 qi and the item you wish to buy is 15000

As that said im 1533 qi black belt , and its asquing 1500, i have the enough money and all but idk what is happening , i restarted computer page and all it and no fix.

The item wants 15 000 QI. You have 1 500. That means you need to play more 13 500 games.

15 000 oh god.. its over nine thousand!!

Yes it is. That's why the set is being sold at nearly 500 000 TC in the market. As is void, demon etc.
