Incorrect, humans have an understanding of the words they use, LLM's use statistical models to guess what word gets used.
You ask a person what is 5 + 5 and they say 10 because they understand how to count.
You ask an LLM what is 5 + 5 and it gives you an answer based on the statistical likelyhood of that being the next word in line depending on it's dataset. If you're dataset has wrong answers you'll get wrong answers.
