I have two different friends from college who were unattached until their late 30s and are both joyfully married now. I don’t know if it makes you feel better, but many of our college friends who married younger are now divorced.
There is no magic time to find the right person. I do think it is important to build a life for yourself that has a rich community — get out there pursuing your own interests, faith life, hobbies in settings that include other people. Don’t do it to find a date; do it to make yourself happy and fulfilled.
Best case scenario is you might stumble across your perfect match doing these things. Worst case scenario is it will make for more interesting conversation with your future dating app dates.
