If it makes you feel better, I have read a few threads on this site where I couldn't tell whether the OP was asking about battery cells or pre-made batteries (packs). In most cases it's obvious from the context. For example, "I bought 4 3.2V batteries. What BMS do I need?". Clearly they are referring to cells. Or "I have a 12V 100Ah battery...". That's likely a pre-made pack since it's already 12V. But when it's not clear, ask. Many questions are posted with missing or confusing info. If no one asked clarifying questions there would be a lot of unanswered posts.
