Fungi can look very different at different times in their life cycle, and so historically that has led to the same fungus being given different names because people saw it at different stages. It's a bit like putting caterpillars and butterflies in different species because they look so different.
It gets more confusing because some fungi are usually seen at the "caterpillar" stage and some at the "butterfly" stage so even once the connection is recognised and officially (since 2011) only one of the genus names should be used, both of them tend to persist in conversation. For instance, Brettanomyces and Dekkera are different stages of the same bugs - and Candida and Pichia are a similar pairing.
And historically Candida was the dumping ground genus for anything that looked like a yeast but they weren't quite sure what it was. There's been a recent paper that sequenced them to try and untangle the mess at a genetic level, but microbiologists will still use the term as a generic one for "looks like a yeast".
So in terms of your sample report, they're saying it could be one of 100's of species of wild yeast that are out there in the environment, it could have come from anywhere. You have them on your skin, it could have blown in from outside, it could have come from anywhere.
