I've thought about this before and it is pretty interesting. She never directly mentions their mothers and she was born after Yang so she would have just always been there. And while it may just be them being very close, she always refers to Yang as her 'sister'. I could actually make for a good plot device aswell, with Yang never telling Ruby about her mother in fear of her trying to help in her search.
