Yes but competition between sellers in most niches is so tight that as a new seller you'll struggle to make profit, even if you've innovated on the product, because you'll be paying Amazon for search engine ads and also dropping your price as far as you can to win sales. You essentially end up as an unpaid employee of Amazon, managing and optimizing a listing.
