In named.stats you copied, no:

"requests" mean all incoming messages from client, including dynamic
update requests and notifies.

"queries" are a subset of "requests" only for messages with opcode =
query.  These are probably what you want to look at in this context.

If all you need is to just count the number of incoming queries, you
can see it in the "Incoming Requests" section of the stats:

++ Incoming Requests ++
               54708 QUERY
                1592 UPDATE
