No, you see 1 _process_. Which may, or may not, have multiple threads.
"man ps" and scroll down to the 'THREAD DISPLAY" section....

# ps ax
 9353 ?        Ss   25462:16 /usr/sbin/named -u bind

# ps ax -L
 9353  9353 ?        Ss     0:00 /usr/sbin/named -u bind
 9353  9354 ?        Ss   5944:29 /usr/sbin/named -u bind
 9353  9355 ?        Ss   5962:13 /usr/sbin/named -u bind
 9353  9356 ?        Ss   5958:40 /usr/sbin/named -u bind
 9353  9357 ?        Ss   5949:14 /usr/sbin/named -u bind
 9353  9358 ?        Ss     0:20 /usr/sbin/named -u bind
