Count district values based on another coulmn

I have an SQL table of people with their event attendance status:

I'm trying to filter and count only the people who never came to any event but can't get the right code to do this.

I was able to get this result using this code:

SELECT "Person" as "Person"
FROM TABLE
GROUP BY "Person"
HAVING (((COUNT(DISTINCT CASE
                         WHEN EventStatus = 'NoShow' THEN 1
                         ELSE NULL
                     END) - COUNT(DISTINCT CASE
                         WHEN EventStatus = 'Arrived' THEN 1
                                               ELSE NULL
                                           END)) > 0))

But using "GROUP BY" won't allow me to count the results.

The expected result I need is: 2 Which is the result these 2 people who are always "NoShow": Isabella Gomez, Ethan Williams.

People who never showed = all people - people who ever showed.

SELECT
  COUNT(DISTINCT person)
  -
  COUNT(DISTINCT CASE WHEN EventStatus = 'Arrived' THEN person END)
FROM
  yourTable
