I just took my Mac book pro to Apple because the screen is not receiving power. I ran out of iCloud storage to back up my data so I was wondering what are the chances that there will be data loss during screen replacement?

Apple assumes the user is backing up their computer and Apple will feel free to erase or even replace the storage drive without asking permission. Chances are Apple listed this in the paperwork you signed.
An independent AASP, may offer to back up your data if necessary if you ask them to do so (at an additional cost). If an AASP is performing the repair in their own shop, then your data is probably Ok, but not guaranteed. If the AASP shipped the laptop to an Apple repair depot, then the Apple repair depot will not ask permission to erase or even replace the storage device if it becomes necessary during the course of the repair.
You should always have good verified working backups of your computers and data. Having backups on at least two different drives is also recommended.
Here is a great article detailing why iCloud is not a backup:

Edit: The answer to your question is data loss is probably slim, but not impossible. If you happen to have the MBPro 13" non-touchbar model with the potential SSD issue, then the chances are much higher you may lose your data. You just never know.

You need to make the backup to an external hard drive, not iCloud.
We aren't Apple but my personal feeling is I won't hand over a computer from repair without having a complete backup just in case of trouble. Apple service docs says it is your responsibility to have a full backup before having service performed.
Always back up your computer before taking it to be repaired. This is especially true if your computer is still under warranty or covered by AppleCare. In those cases especially the tech is likely to inspect the entire computer and fix everything that is wrong. Case in point: I send my wife's MBP to have the trackpad replaced. It was returned with a new bottom case, new display (and top case) new fans, and of course, the new trackpad.
You should always have a backup. Anything could happen during repair. And as already stated, iCloud is not a backup.
What are the chances that there will be data loss during screen replacement?
