They are all about the calculations.
The first number (7607484416) is the number of bytes copied so far. The second number is this interpreted as the SI unit Gigabytes (1 GB is 10003 bytes). The third number is this interpreted as the IEC unit Gibibytes (1 GiB is 10243 bytes). Notice the difference between "GB" and "GiB".
