You can have six-pack abs and still have gynaecomastia.
Gynaecomastia is not only about body fat. Hormones, genetics, puberty, medications, steroids, and even normal developmental changes can cause gland enlargement.
That’s why some extremely lean men still avoid tight shirts or swimming pools. The chest does not always reflect body fat percentage.
This is not always a weight problem. Sometimes it’s a tissue problem.
