What is the context of these two statements?

In fact, inside these processors there are simple queries that look similar.
I just want to understand what this @ means and what it is used for.

There is no mention of the @Call syntax in MySql documentation: MySQL :: MySQL 8.0 Reference Manual :: 13.2.1 CALL Syntax[^].
As Richard already asked: What is the context of such statements?
