Is it unusual to begin a degree at 23?

I'm 22 now, and I've almost completed a 60 credit module with the Open University - and doing so will get me a place at Exeter University, which I will start in September. By the time I graduate, I will be 25/26.
Will I be out of place at all? Will it affect my life chances in the long run? I want to become an academic or a journalist (I've been writing since I was 20, and have been published on numerous political outlets). I know I'm most likely overthinking things, but it has been playing on my mind a bit lately. Any reassurance would be great.

You probably won't have as much in common with freshers but age isn't an issue at uni at all

Well an obvious difference I can think of is drinking/partying. I would have done this at age 18, but it's not something I'm interested in now. This will probably be beneficial for me in terms of my studies however.
