"I am much better than him" expresses the speaker's view that he is better, more capable or more valuable than the other party. "He is not as good as me at all" further emphasizes the speaker's view that the other party is not as good as himself, and uses the derogatory term "fundamental" to emphasize this difference. This statement is disrespectful to others, because it directly devalues the value and achievements of the other party.
