At 31 years you are quite young still. Some of my peers studying maths are around your age or older than that. Don't be afraid to dive into maths if you feel like it. Anecdotally people >25 do better than younger people. Maturity appears to be an asset sometimes. Yes, young people might think and learn slightly quicker, but older people tend to be less easily distracted and more focused on the task at hand. Maths is not a race though, so I believe age is an advantage at the end of day.
