Do people make money on Gumroad?

I've been hearing a lot about Gumroad as a platform for creators to sell digital products like e-books, music, and software. But I'm curious, do people actually make money on Gumroad? Is it a viable option for those looking to monetize their creative work? What are the success stories and potential challenges that creators face when using this platform? I'd love to hear from those who have experience with Gumroad and can share their insights on the earning potential and overall experience.
