“I'm one of those people you hate because of genetics. It's the truth”

Simplified Meaning:

Some people are born with certain advantages that make life easier for them, and this can make others feel jealous or resentful. Imagine a student who always gets good grades without studying hard, just because they naturally understand the material better. Or think about an athlete who can run faster and jump higher without much training, simply because of their natural abilities. This can be frustrating for those who have to work really hard to achieve similar results. The person in the quote is acknowledging that they have these natural advantages. If you're feeling envious of someone like this, try to focus on your own strengths and work hard to reach your goals, rather than comparing yourself to them. Everyone has unique talents and abilities, and finding your own can help you feel more content and successful in your own life.
