I don't know much, but my guess is that I created a partition of 50GB of 1TB but there is still 950GB left. How do I use the 950GB? Do I create a new partition to use the 950GB?
Will it erase the data in the 50GB partition?

Yes, you need to create a new partition. No, that shouldn't affect the existing one (but it is always good to back up your data before making any change to a disk). Think of your disk as a library. If you have built a new library, that library might have a lot of space, but you cannot use that space until you have added some shelves to store books. Similarly, you can't use your disk until you create a partition and format (this creates a filesystem) it.
You have installed a few shelves (one, small partition) so that's the only part of your "library" (disk) you can use. To use the remaining, empty space, you need to add shelves, to make a new partition and then format it to the desired filesystem, most likely ext4.
So, use the tool in the screenshot, and create a new partition taking as much of the space as you want it to use, and then you will be able to store things in that partition.
