random – How to count the amount of times an element appears seperately within a nested list


Beginner at using Mathematica, and having trouble with nested lists. For example, the following output for 15 coinflips every day for a year:

cointoss1 = Table[cointoss2 = RandomChoice[{"H", "T"}, 15], 365]

Which gives an output like:

{{"H", "T", "H", "T", "T", "T", "T", "T", "H", "T", "T", "H", "H", 
  "T", "T"}, {"H", "H", "H", "T", "H", "T", "H", "H", "H", "T", "T", 
  "H", "T", "H", "T"}...

My question is how would I be able to count the number of times I get a certain element in the list. For example, If I wanted to count how many heads I get within each list how would I go about doing it. I’ve tried using count –

Count[cointoss1, "H"]

Every time I tried it I have gotten an output of 0. I want to get it in a list like output for the number of heads in each list:
{5,8,…}
Another thing I want to find is the number of lists with x or more heads. So how would I go about doing this? Apologies for the bad formatting, this is my first question.
