Difference between netstat & rndc status

Let's begin by showing your bind tcp and udp connections, 
netstat -tunape | grep named | wc -l

Hello Admins
When i run :
#netstat -an |grep udp |wc
it returns a number which is lower than the output of rndc status recursive clients.
what is the difference between netstat -an |grep udp |wc(open udp ports to dns server) and amount of recursice clients in the rndc status command?
I thinked they should present the same value? doesnt it?
Does the difference point the cache hints?
here is my values:
ns1# netstat -an | grep udp | wc
     630    3150   42210
ns1# netstat -an | grep tcp | wc
      22     132    1669
ns1# rndc status
version: 9.7.3-P1 (version not currently available) CPUs found: 4 worker threads: 4 number of zones: 18 debug level: 0 xfers running: 0 xfers deferred: 0 soa queries in progress: 0 query logging is OFF recursive clients: 1497/9900/10000 tcp clients: 3/1000 server is up and running

Not the same stuff at all.
netstat -an|grep udp shows the UDP concurrent connections currently.

> recursive clients: 1497/9900/10000

This shows the history count of DNS replying.
