Can I get back an old domain name?

I’ve had https://joshrachlis.wordpress.com forever, and wanted to change the name, but I read that if I do that, I can never get that address back for anything. So, 2 weeks ago, I started https://sparkthegenius.wordpress.com, but haven’t posted anything yet. Then this week, I moved my podcast hosting service to Spotify – https://podcasters.spotify.com/pod/show/sparkthegenius – and they have a feature Connect To WordPress, where you can start a blog to have your podcast on. But, if I do that, I can’t get sparkthegenius. But if I delete the other blog, is that name gone forever?
