What's the meaning of one's in this sentence?

The thought is that if they are one’s the collective members support and think provides value in conjunction with 1 or 2 active members will help sustain sub-groups.

I can not fully understand one’s meaning, thanks very much!

It looks to me very much as if the writer havs mistakenly included an apostrophe. I suspect it should be “ones”.

oh, It seems so, thanks very much!
