Drop shipping has become one of the ways you can do business without a large amount of capital. Please do the research before you jump into it.
You need to choose reliable suppliers you can get your goods from. You can then join sites like Spotify, Amazon or eBay as platforms where you can sell your goods.
I always recommend Oberlo as an easy way to get into dropshipping. It does everything for you. However, I think they only use Alibaba as suppliers.
