so the question was, when calculating theoretical complexity of hashed data, can i neglect the fact that, for every checkup, it has to go through all hash keys to get me the value for my checkup

There's no need to go through all hash keys, you're directly accessing element you're need (it's practically O(1) operation), so yes you're calculations are correct. Note, that the same is true for accessing DB record using index
