Do these sentences mean the same thing?

A. ... the doctor couldn't recognize a sentence.
B. ... the doctor couldn't understand a sentence.

No native speaker would express that idea in that way.
Most native speakers would say: "The man kept on speaking incoherently, and the doctor couldn't understand a word".
Some native speakers might omit 'on' after 'kept'. But "couldn't understand a word" is almost a fixed expression in English. Certainly nobody would use 'sentence' in that context.
The other possibility is: "...couldn't understand a word he was saying."
The answer by Clickvalley seems not to address what you are asking about.

They do not all mean the same thing. The first sentence says to the listener that they are not great - and the reason they are not is that they know many things. The second means that they are great, but not because if that. However, it is not optimally phrased.
