You are definitely not too old, I started uni (through an access course) when I was a few years older than you and five years on I just got my final degree result! Far and away the best thing I have ever done and I can honestly tell you that it's not that the age difference didn't matter as such, it's like it wasn't even an issue, if that makes sense? No one even asked me my age to be honest, I assume they must know I'm a bit older but it just wasn't a thing. Go for it and good luck.
