In the end only kindness matters...

Yep, what you wrote is correct. However, a woman can create her own chances, and do things to increase the probability of success. I've done it my entire life. If you're less attractive, sometimes you just have to work harder. That's all. :) Personally, I do not use any type of sexuality to get things, at least not consciously. It's the most classic form of manipulation and control. Men do it mostly with money and power; women, with fucking. It is just the way of the world, but there are always exceptions on both sides. :))
