ACL random uses the operating system random() number generator.

A new random number is selected each time the ACL is checked. The ACL
will declare match vs. no-match depending on whether that number is
below or above a defined squid.conf threshold value.

Not using ACL random.

For certainty you need one of the many load balancing cache_peer
selection algorithms. Which naturally require the server(s) to be
cache_peer.
