Does mysql “order by” guarantees to give the same order for the same query every time if the sort key is equal?

I’m planning to write a query that sorts the result by a value s and then paginate the result. Let’s say I have ten items that match the query and all the items have the same s. In the first query, I sort the value by s and get the first five items. Then in the next query, I sort the value by s and get the sixth to tenth items. Is it possible that the items that appear on my first query will appear again in my second query, and that some items will not show up in either query?
