I am unable to understand the diff between the objects and the files in a bucket. Could you please help?
All files on the bucket are objects. GCS call them objects because they can be anything. The files that sit on your local computer are files because they have properties within your local computer, e.g. Microsoft Word files (.docx) can be opened by Microsoft Word. GCS just treats .docx files, .jpeg images the same as lumps of code, which is why they are called objects.
