This depends on your system configuration.  nginx itself 
does not use the DNS servers defined by the "resolver" directive 
during configuration parsing, it uses getaddrinfo() and/or 
gethostbyname() library functions.

Note that resolv.conf is not the only configuration file to 
configure system name resolution - on most systems, there is also 
/etc/nsswitch.conf and /etc/hosts to consider.
