Everybody and their cousin started a copywriting operation. Some businesses and brands started using mostly AI to replace copywriting tasks. You have competition up to the bum for it nowadays and most people making money from copywriting aren't doing any copywriting but make money selling courses to low skilled people that will also be your competition.
The flipside: There will always be a need for copywriters e.g. online businesses needing weekly newsletters, sales offer emails etc. You should focus on the skills to help you reach out to these businesses just as much as the copywriting itself. Cold emails, calls to local businesses etc. Can even offer your services for free at first until you get rolling. Find out what type of copywriting businesses need and a way to pitch it.
