Hi @Faisal Noordeen ,
According to the description in the official document you provided, the upload limit of a file in a document library is 250 GB.
Now that you can store it, you can copy and move it. Through my understanding of the official document description, the transfer of a single file does not limit the file size, however there is a limit to copy/move multiple files together, as mentioned:
In addition, the applicable scenario of 2GB you mentioned is when using some SharePoint APIs, not for OOTB copy/move.
