Is this really gyno? or am I being gaslighted by my friend?

21M, 182cm, 70kg, ~20% body fat. My friend says that this is definitely gyno, all this time I thought that this is just normal chest fat and it will go away as I get leaner. It's been a year since I have been hitting the gym. Is it really gyno? should I consult a doctor?
