as a UK seller, can I still make money without the FBA badge ?

Hi, I have been selling on ebay for a while, I have some inventory in the basement.

I don’t want to ship my inventory to amazon, as I am selling the same items on Ebay, so my question is : can I still make money if I am not FBA verified ? (in other words, if buyers don’t see my listings marked as prime/fast shipping by amazon)
