How much is Martial art training dependent on having some talent? Or being athletic?
Like anything else, there are people with a natural aptitude for it. Being athletic will generally help, unless you're doing the wrong kind of training. Most striking martial arts (as opposed to grappling) require explosive power, so sports where you train with a lot of explosive lifts, short sprints, etc. will help you more than being a long distance runner. While stamina is important, it's really a case where you need to be able to perform at peak for 2 minute intervals as opposed to constant extended endurance. Flexibility is also something you need, and it's probably the most important factor to have to begin with (or you'll have a lot of injuries), luckily you build flexibility faster than strength.
The large part of martial arts training is reflex reconditioning, i.e. turning your reaction when a punch is being thrown at you from, "No! No! Not in the face!" to block and counter. There's also learning how to take a hit in order to mitigate the damage (ride a blow), mental preparedness and experience from sparring. Anyone who keeps at it will get better, however not everyone will be going around winning tournaments. Most people can beat a person who is too levels lower than them in training as long as that person doesn't have an overwhelming physical advantage (reach, strength, etc.)
If you just want to learn self-defense I recommend Krav Maga, it's a martial art that will make you effective with the minimum of training. Over all, Brazilian Jiu-Jitsu and Wing Chun kung fu will make you the most effective if you stick with it. That's not to say good old fashion boxing, karate, etc. aren't effective, you just need to find something that suits your personality.
Wouldn't be Christian to just let it go or does that not solve the problem?
It depends on the individual and how the incident psychologically affects them, some people can't let it go. Martial arts can build confidence and help a person work through feelings of inadequacy they have after being assaulted. It can also make them hyper-agressive, which you want to avoid. Sometimes therapy or time is enough, other people need to feel like they're doing something proactive.
