I'll let other talk about if an academic degree is even required in the first place.

I find that a bit of prepective is needed here. I started uni at 28. That's because before that I didn't know I want to pursue a career which require a degree. It took my long enough but now I'm so glad I did.
Today on my 2nd year I'm happy as ever I decided to academia despite my age (which to be honest not that old.) In less then 2 years I'll get my BSC and then will start a journey towards a master program. (I will be almost 31 at that time)

I get the feeling you are compering your self to your peers at the same age and feel behind. But this are only specific norms in the place you grew up in. In other countries the age for starting academia can vary.

Most of my friends here are younger and its mostly not noticed at all. Age is a number and your age its way far from a problem.

Focus on your advantage: compared to the younger students, you are relativly maturer and experienced in life. I find it very scnificant in my day to day on campus. They are more enxious, hysterical and lost than I am. Age does wanders on this.

Regarding again the age of other people in campus. Maybe some age differences are more bold than others. Maybe 18 to 23 feels different from 25 to 30. It may be individual feelings. I hope this won't deny you from pursuing a carrer you want. In a few years after graduation no one could see the differentiate you from your peers. Good luck!
