Go (and in most programming languages) uses a hash table under the hood in the Map data structure. Key collisions are possible — situations where different keys have the same hash value.

Go runtime handles these collisions using internal mechanisms, such as chains or alternative collision resolution methods, to ensure correct storage and retrieval of values by keys.

Therefore, key collisions are possible, but they are hidden from the user and do not affect the correct operation of the Map.
