Is there a limit to the number of subdirectories I can create?
I am using Ubuntu 18.04.2 LTS Release: 18.04 and I want to know if there's a maximum of directories that I can't go beyond?

Yes, for ext4 systems every file or directory uses an inode, of which a limited amount are pre-allocated when the disk is first formatted. You can see what percentage of this is used by running this command:
df -hi
Look at the IUse% column. For most situations this never be exhausted, but it's possible this can lead to problems if you start out on a small disk (and therefor not many inodes) and later resize to a larger disk since inodes are not re-allocated when growing a partition. In those cases you would want to copy the file system from a small disk to a larger disk in a special way.

Outside of the inode limit, there's also the path length limit, so while you might be able to create a 1000 directories, you might not be able to do/1/2/3/.../1000.

There isn't a "strict" limit on total path length, only each individual file name itself. A program that uses relative paths can address paths of infinite length, see serverfault.com/a/9553/46631
