What is a SteamID64?
A SteamID64 is a unique 17-digit number that permanently identifies a Steam account, for example 76561197960287930. It never changes - even when the player renames the profile or changes the vanity URL - which makes it the canonical key for any Steam-related lookup.
STEAM_0 vs STEAM_1
Both point to the same account: the first digit is the Steam "universe". Legacy tools print STEAM_0:1:39075162, modern Source games print STEAM_1:1:39075162 - the rest of the id is identical, so converters treat them as equal.
