I observed that query count is a difference between Click House DB and QAN.

Your query in Explore counts the number of Clickhouse lines with this fingerprint.
What you need is the sum for the count field.

As per the below screenshot, the Yesterday query count is 7137 times?

Here is my example:
The numbers are matching.
