Information for a beginner for the managment of the personal account

Hello everyone, I created my Adobe Account  like three months ago but I still not have earned any money yet, does someone know if in the personal page there is the possibility to control if some users have demonstrate interest in my photos, or if some of my pictures have been sold, but not enough to receive the minimum of the payment from the website? How can I improve the visibility of my personal portfolio?

And also, is it normal that in the section "my library" there are no picture? What's the difference between my library and my portfolio?

Thank you for the attention, I hope someone could help me to understand a bit more of this platform. 

(Yes, I'm a perfect amateur)
