If a phone has a battery capacity of ~2k mAh, and a power bank has a capacity of ~10k mAh, am I right in thinking that the power bank can deliver approximately 5 full charges to the phone? Or doesn’t it work like that?
Essentially, yes. It won't quite do five full charges as there will be some losses in the charging circuit, but as a rule of thumb it'll be close enough.
