So, let's see how things look objectively. At the age of 23, as far as I understand, without physical training and a special culture of movement, without training / systematic physical and aerobic exercise for many years and a sedentary lifestyle. Do you still want to focus on a new sport that you can do professionally to the point of competing and receiving awards, medals and cups? You obviously are not interested in the only sport you practiced as a child (basketball) and in which you probably have some basis. Martial arts, which allow you to start at a later age and appear in competitions, do not attract you. You can't swim either, and once you point it out, I guess you don't want to learn. So, how to make the number from the couch, on the award ladder? What is your attitude to the riskier sports - skateboarding, old bike? Or to competitive cycling - there are also a lot of tournaments and competitions and it is relatively safe, and the average age is higher? Sport climbing is also a good idea - there are also not started from an early age, and there is an opportunity to train not only outdoors but also in the gym. But again, endurance, flexibility and more specific qualities and physique are required. It's hard, and you're not angry, but you sound a little spoiled and grown in a pot "the sea is knee-deep" type. Except to suggest you try chess? In terms of physical condition it will not be a challenge, you will also have the opportunity to participate in tournaments. However, it requires highly developed logical thinking and combinability, which, given the nature of the topic and the questions asked, seems to me to be a challenge. So what's left? Professional billiards? Badminton? Folklore dances?

Of course, it is not too late to do sports for the purposes he described. It is too late only for a professional sports career.
