You are right. The general advice is that one output driving around
three inputs on different devices is OK for a typical line level 
output on the professional equipment. No problems should arise here, 
unless you have your output connected to many devices and some 
of them are not powered up (some devices can cause distortion 
to signal on the line when they are not powered up). 

In case you want to drive very many different inputs from 
one mixer output, the best advice in this case it to get 
an audio distribution amplifier that has enough many ouputs 
so that you have one output for each device you want to feed the 
sound to. Distribution amplifiers are just designed for this use.
