According to the docs at
it will.

The StartServers directive sets the number of child server processes 
created on startup. As the number of processes is dynamically controlled 
depending on the load, there is usually little reason to adjust this 

The default value differs from MPM to MPM. For worker the default is 
StartServers 3. For prefork defaults to 5 and for mpmt_os2 to 2.

The *ServerLimit* directive oth puts a hard limit on the numkber of 
children Apache can start.

For the worker MPM, this directive [ServerLimit] in combination with 
ThreadLimit sets the maximum configured value for MaxClients for the 
lifetime of the Apache process. Any attempts to change this directive 
during a restart will be ignored, but MaxClients can be modified during 
a restart.
