That's a very broad judgement passed.
Women help in different ways and men help in different ways.
In my past experience, Men friends will stay late with me, arrive at short notice, help out with physical effort, often lend money even if they are in hardships. But they did these because they could. Girls in my circle were not allowed to stay out late, had to answer to parents on every penny, were often very weak physically and had less social interaction. They themselves also had limited social circles to borrow help from.
I have known people from both genders going out of the way to help their close friends. It's usually that girls have taken a lot of times to form close friendships whereas guys hit it off very quickly. On the other hand, girls are more empathetic and good listeners while even close guy friends Crack jokes and belittle your concerns.
