Centuries ago, Nostradamus foresaw when Jean-Francois.Doyon@CCRS.NRCan.gc.ca would write:

I'm not sure why you are surprised at this. You asked to order them
primarily by random(), and then by id, if the random values were
equal, and that is clearly the order that you are getting.
If you want to order the 10 records by id, you might accomplish that
by the following:
select * from (select * from tablename order by random() limit 10)
order by id;
