Top sellers have on average more products listed than those who are not as big. This is because many of the top sellers are resellers doing retail arbitrage, with access to thousands of different brands.
Those who use Fulfillment by Amazon (FBA) have on average less products listed than those who don't use FBA (referred in the table below as Fulfillment by Merchant (FBM)). This is because listing products when using FBA requires sending those items to Amazon. For example many of the books sellers have hundreds of thousands of products listed, and are rarely using FBA because of storage fees.
