Is it true that key collisions are possible in a Map data structure?

In the data structure Map in Go (and in most programming languages), a hash table is used under the hood. Collisions of keys are possible — situations where different keys have the same hash value.

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

Thus, key collisions are possible, but they are hidden from the user and do not affect the correctness of the Map.
