Hey there. They are just different readings for the same kanji. For example, you've seen this kanji before「一」and what do you know it as? Probably, 「ichi」, because it's the number 1 in Japanese, right? Cool. Then, maybe you also know this kanji: 「人」 and this one you probably know as 「hito」 because it means "person. Awesome.
Now, what does this compound kanji mean? 「一人」. If you guessed "One person," you're correct. However, is not 「ichi hito」. It is pronounced 「Hito ri」. Another reading for 「一」 is 「hito」 and another reading for 「人」 is 「ri」, often when it's being used to make compound kanjis.
It can be confusing, but it's better if you learned vocabulary in addition to the different readings, so that you can understand what they mean. Learning different readings without any context is not helpful.
