No one is ever too old to learn about horses or to take lessons! There is a wealth of information that comes when taking riding lessons, and plenty more opportunities to learn and grow as you spend time around the barn. If you want, you can make a few calls to the stables that you are interested in, and ask about their lesson program, and if you can have a tour before choosing to ride. You can get a feel for the instructors there, the lesson horses, and even the other students or boarders around the barn. You may also want to think about whether you want to do English, or Western riding- which style do you prefer. If you are unsure, maybe find a barn that offers both Western and English lessons, that way you can try out both styles of riding! :)
