Well, yeah. Admittedly the phrase "being good with people" is kinda vague. In most jobs you have to deal with people in some way or another. But when people use this phrase, they often mean something similar to "extroverted", "talkative", "persuasive", etc. Like for jobs in sales, these qualities (?) are often required and expected. However, I don't see how they matter much in a desk job, assuming you manage to communicate well (in some form or another) with your co-workers and clients.
