This hasn't been true since FreeBSD 5 and the introduction of Yarrow;
/dev/random and /dev/urandom are one in the same:
lrwxr-xr-x 1 root wheel 6 Jan 1 1970 /dev/urandom ->
random
-% dd if=/dev/urandom of=/dev/null bs=1M count=512
512+0 records in
512+0 records out
536870912 bytes transferred in 9.997684 secs (53699528 bytes/sec)
-% dd if=/dev/random of=/dev/null bs=1M count=512
512+0 records in
512+0 records out
536870912 bytes transferred in 10.036211 secs (53493386 bytes/sec)
