Everyone says nothing is a scholar. Is this correct?

Of course not. The context of this sentence is that in ancient times when science and technology were underdeveloped, not many people could change their destiny by knowledge, but more by their own family background. That's why there are such words.

But in today's society, knowledge is often the only way for children from poor families to change their fate. And now the technology is so developed, it is also developed by the scientific research of these scholars.

So it is not appropriate to say that you are not a scholar now.
