Are "full-time hunters" and "hunters" the same thing? Why are the names different?

Full-time hunters and hunters are the same cartoon ~ because fans like to abbreviate their favorite cartoons ~ for example:

Young Master of Yin and Yang-Shaoyin

Naruto-Naruto

Legend of the Magic Warrior-Magic Warrior

By the way, I have to remind you that some single cartoons have several names, all because the translated names are different in different places, but don't worry, they are all the same cartoons ~!
