How many products do you need to sell before you start to get ungated in diffrent products ?

As a fresh seller still maybe like 1 actual month of selling should I try to get ungated in anything? Or do keep selling what I can untill im auto ungated ?

If I find an identical product with diffrent packaging but Im sure its the same can I sell it ?

These last 2 weeks I have been sourcing for hours a day using diffrent strategies. I found some products with potential but now when I go to source I feel stuck and going in a cirlce because im seeing the same sellers and the same products. I feel like im struggling to finding new sellers. If anyone has any advice that would be very appreciated !

is it ok to source from aliexpress? Should I try if theres already 15 buyers but buy box is constantly rotated
