Both are true. There are more male-focused stories, and boys are not taught to care about female-focused stories, and this goes beyond film and television and into books. JK Rowling famously went by "JK" instead of her first name (when she didn't actually have a K middle name) because publishers knew boys were less likely to read a book by a woman.
