With an up-to-date firewall, do the OSs behind the firewall pose a risk?

Say you have an updated firewall, how would having older obsolete versions of operating systems behind the firewall post a security risk?

I'm standing up my understanding of IT security. I thought that having a modern firewall would prevent most attacks from penetrating a network. Once a malicious actor is in your network, does it matter what versions of server and workstation operating systems exist behind your firewall? I'm guessing that more modern OSs would slow the attacker's advancement in your network and the attacker wouldn't be able to utilize known exploits to access the data in these various servers/databases. Older versions of operating systems might also give your attacker places to hide.
