Correct, Noise Isolating means they are essentially earplugs.
Noise cancelling uses microphones that pick up background noise, and play the inverse frequency in your earphones, thereby "cancelling" that noise.
Noise cancelling works for low-pitched droning noises like airplane engines, air conditioners, etc. Noise cancelling will NOT prevent you from hearing your giggly co-workers. In fact, since noise cancelling works with microphones, you will actually hear your co-workers quite well.
I used to be a frequent flyer for work (clocked over 250k miles a year), and believe me, you will hear voices just fine.. dammit!

Does "noise canceling" imply some kind of electronic masking of background noise, like by generating a different noise? And how might that work on high pitched sounds, like the squeals of giggly co-workers?
