latency and GRBL
True. But it's all installed at the same time as far as I can tell. So why differentiate?

Nor does that answer my question that may not have been asked correctly. Which is "Will latency be an issue when using a Linux PC running LinuxCNC when sending commands to a GRBL based CNC? In other words, do I need to worry about latency when selecting a PC for my application? Or will any Linux capable PC do the job?

Thank you. I just found another reference that reads pretty much along those lines. So, a PC capable of running LinuxCNC (Ubuntu) is all I need to worry about at this time. Latency won't be an issue until I go bigger and utilize a real "motion control board".
Question answered, IMO.
PS It’s been a long time since linuxcnc came with Ubuntu. The Ubuntu Linuxcnc ISOs are very obsolete.
