This relates to how it’s possible to recover deleted data. When you “delete” something you are removing the thing that tells the computer there is data there. All those 1s and 0s stay how they are, the data is still there. It remains there untill that specific spot is reused, at which point the 1s and 0s are changed to whatever is being written. It is impossible to move data on a computer. What you are really doing is copying it from the first place to the second, and flagging the original location as free.
Think of installing an application as putting a desk together. You have to unbox everything, make sure you have all the pieces, put it together per the instructions, then place it in your home and fill it with items you’d use with it. That takes time. When it’s time to get rid of the desk, you remove things from the drawer and take it outside. Way less time.
Installing software is similar. Installers are compressed, so it has to uncompress the files, make folders to hold everything and fill it with specific files, then make sure your computer knows where necessary files for the application are and what to file types it can open. When it comes time to delete the application, it’s just deleting the folders it created and removing references to the application that it set up during install. It’s not always far faster to uninstall than install, but this is a reason why it can be.

Writing in the disk is equivalent to writing in a book, while uninstalling a software or deleting a file is more like deleting an entry in an index. This is why it’s possible to “undelete” a file in certain cases.
