A casualty was a person who suffered an accident, injury, or other trauma. It often referred to fatalities, but non-fatal injuries were also considered casualties.
Military use indicated those combatants rendered combat-ineffective, whether by death, injury, or capture. Civilian casualties was a military term that described civilian or non-combatant persons killed or injured by military action. (TOS: "A Taste of Armageddon"; VOY: "Memorial")
During wars, such as the Dominion War, the numbers of casualties would increase significantly, especially among military personnel. (DS9: "In the Pale Moonlight", etc.)
During Earth's World War III nuclear weapons accounted for six hundred million casualties. (VOY: "In the Flesh")
