Ok, so I looked it up on my professor's notes and found the answer. about 2% of the genome is made up of genes.

Less than 10% of the human genome is composed of genes. The rest of the DNA is repetitive junk DNA.

Your professor is right because that's what my professor and my book say. The rest of the DNA is "junk DNA" which doesn't get coded to RNA or "pseudo genes" which at one point in our evolutionary history were inserted into our DNA by viruses. But Yes, only about 2% of our DNA is made of coding genes.

98.2% of the genome, according to the recent estimate, contains sequences that are non-coding, variously named satellite DNA, repetitive DNA, junk DNA, retrotrotransposon etc.This means that coding genes constitute about 1.8% of the genome.

I have always heard 3%, but that is close enough. Yes, the rest is- unfortunately- called junk dna. Basically the junk dna is the "stuff" scientists don't really understand yet(and, yes, a real scientist would say that) - but I have heard that they consider some of the sequences parasites that live in our dna just to reproduce
