is digital content/downloads a saturated market now?

Ive dabbled with digital downloads to sell on my etsy shop. none of them have sold. however i am wondering how these "passive income hacks" of creating and selling digital items is really worth it. i mean it seems like there are just too many digital download shops on etsy etc, how do you stand out? how do you make a difference, besides marketing and promoting? if its sooooo over saturated, paying the $ to start a shop and not get any sales would suck. it does suck. oh but "you can spend 15 minutes making one thing and sell it 32490273 times and make 1.3 million dollars"....bet. nowadays, without an ESTABLISHED shop that has been in the digital download business for years, is it really worth it? can you make money posting a digital download once a day and make enough to get divorced?

just asking for a friend lol
