There are two major types of massage: that just for relaxation and then that for medical treatment. Massage therapy schools teach you to do the latter, that is, offer massage as a medical technique. There are more than 80 different modalities possible: that is, 80 different known and approved methods of giving a massage. Each of them has its benefits and can and is used to treat different conditions. The type of massage used on a sportsman after training is different from that used on a bad back, different again from muscular injuries and again from that used on those with chronic problems: say, someone bedridden through paralysis. No one will expect you to master all 80 different types: you'll be encouraged to specialize in a few and in a specific field, say, sports massage, or occupational therapy. What is a career as a masseur like? Because it's a very physical job, full time is considered to be 30 hours a week or so and earnings are good. Because there are so many different types of massage which can be used in so many different fields (sports, rehabilitation, hospitals and so on) attending massage therapy school is essential: but after you've finished there are many different places you can work. With sports teams, hospitals, care homes, gyms or independently. As both the population ages and massage itself becomes more popular jobs are expected to grow quickly: those qualifed from amassage therapy school will have the best choices, of course.
