Is OCD more controllable with age?

I am currently an 18-year-old undergrad and have been undergoing OCD symptoms since the age of 12. I have symptoms like counting words while reading, rumination, anxiety, depression, and compulsive check.

Despite my treatment, I still feel like the symptoms are there. I do feel better but it is still there. May I ask if OCD can be more controllable when we reach the age where our brain is fully developed? I've heard that the brain is done developing at 25, and that's when everything starts to get easier (at least for people who don't have OCD to control their emotions).
