Yes, you can position controls with the X and Y properties, but only so much as within their container. In this case, your container is the datacard. However, the datacard plays a special role and the designer controls the actual X and Y based on how you configure the form (in this case).
You can use the Form in PowerApps and customize it as you like to the constraints of the datacard positioning (to be absolute). You can turn off the snap columns option on the form to adjust more, but overall, the form itself is limited.
You could create the screen with your own hand placed controls and then wire up all the display and writing logic to the list.
OR, you can use both! If you are just starting out with PowerApps and forms, it might be a little advanced to do, but you can use a Form and separate the visual from the form in such a way that you have complete control over what you want to be seen and yet have all the full-functionality of the form to rely on.
If you want to get deeply aware of forms and their feature and functions, I have an educational training video on them. It's quite lengthy and in-depth. So it will tell you most of what you ever wanted to know.
Specifically in regard to styling your forms, Part 2 of the video goes on to explain some of the basic styling you can do, and Part 3 describes how to separate the display from the form and still use the form easily.
Perhaps worth having a look as you embark on this project.
