Note that that's not a one-time failure rate
That's typical odds of getting pregnant after one year of routine sex while using that method of birth control. The wide difference reflects differing source's interpretations of what level of ignorance qualifies as using.
For instance many teenagers and young adults believe that they are properly using condoms if they make sure the condom is on when they orgasm. Some studies would include these misguided souls as using condoms, others would not.
