MySQL Offset is used to specify from which row we want the data to retrieve. To be precise, specify which row to start retrieving from. Offset is used along with the LIMIT. Here, LIMIT is nothing but to restrict the number of rows from the output.
Limit Data Selections From a MySQL DatabaseMySQL provides a LIMIT clause that is used to specify the number of records to return. The LIMIT clause makes it easy to code multi page results or pagination with SQL, and is very useful on large tables. Returning a large number of records can impact on performance.
To limit the number of rows returned by a select statement, you use the LIMIT and OFFSET clauses. In this syntax: The LIMIT row_count determines the number of rows ( row_count ) returned by the query. The OFFSET offset clause skips the offset rows before beginning to return the rows.
You use the LIMIT clause to constrain the number of rows returned by the query. For example, a SELECT statement may return one million rows. However, if you just need the first 10 rows in the result set, you can add the LIMIT clause to the SELECT statement to retrieve 10 rows.
It will return 18 results starting on record #9 and finishing on record #26.
Start by reading the query from offset. First you offset by 8, which means you skip the first 8 results of the query. Then you limit by 18. Which means you consider records 9, 10, 11, 12, 13, 14, 15, 16....24, 25, 26 which are a total of 18 records.

And also the official documentation.
OFFSET is nothing but a keyword to indicate starting cursor in table
SELECT column FROM table LIMIT 18 OFFSET 8 -- fetch 18 records, begin with record 9 (OFFSET 8)
you would get the same result form
SELECT column FROM table LIMIT 8, 18

You will get output from column value 9 to 26 as you have mentioned OFFSET as 8
