> I once ordered shampoo sold my Amazon that was obviously fake, and then I searched around and realized Amazon has a program where they gather the products from different sellers and put it in one huge bin and call all of them sold by Amazon.com

This is a common scam. Third party sellers will send a fake product to Amazon to be FBA (Fulfilled by Amazon). When someone buys this product from the seller on the product's webpage, the seller is hoping the buyer will actually receive a genuine Amazon product instead that happens to already be in the warehouse. The buyer will be happy and will not complain, so the seller receives their money. However that fake product is still sitting in the warehouse, and when some unlucky buyer receives the fake product, they'll demand a refund. Some unlucky third party seller will have to foot the bill for that refund.

Youtuber "chaseontwowheels" ordered a $6000 camera Sold and Shipped by Amazon.com. He instead received a box of rocks. He got a refund from a suspicious Amazon and shipped him another camera. While filming a video about the incident, he opened the box and it was rocks again. He ended up buying the camera from B&H and finally got the legitimate product.

I've run into a similar problem. I ordered an electric beard trimmer and the box looked new but there was hair inside so it was obviously used. There were a lot of recent reviews about this from different sellers. I'm assuming some third party seller sent a bunch of returned stuff to Amazon and they threw it all into the same bin.
