Yes! Massively. It gave me my career!
I did creative writing at two universities, and the experience was VERY different at both. One was very intellectual - and I don't mean that in a disparaging way. The tutors liked to see stories as games played with language. They'd tell us admiringly about writers who had rewritten the whole of Othello, without using the letter o. Stuff like that. It was really fun, but sort of unsatisfying too, because we were looked down on a bit if any of us created something with a narrative.
'I found it a bit "pop",' they used to put in the margins. I found it hard to see how that word could be used as an insult.
So I went and did a course specifically for writing for children, at Bath Spa University. It changed my life. The tutors were all published authors, and they gave us really helpful tips about the BUSINESS of writing. How to write a covering letter. What to do when you get a rejection. The pros and cons of having an agent.
And not only was everyone LOVELY, they were all so blimmin TALENTED, too. About six or seven students from my year have gone on to have things published.
At the end of our course, we put all our best work into an anthology, and sent it out to publishers and agents. From that, I managed to get some interest, and eventually a publishing deal.
So I'm massively in favour of creative writing - as long as they are the RIGHT ones for YOU. Don't carry on with a course if you feel unhappy, if you feel like you aren't learning anything, or if you feel that everyone around you is dreadful.
If you're going to spend time, effort and money doing something - it has to be USEFUL.
