No. Vim gets its keyboard input in "cooked" mode, and that means that if
you hold down the s key, after a short time (configurable in the BIOS at
boot time) the keyboard repeat will kick in and you will get a string of
s letters. That string will stop if you press 1 but Vim will have no way
to know that the s key is still down.

What you can do is have Vim type "Hello world" if you press and release
s then press and release 1. See :help "map.txt" and check both mappings
and abbreviations. If, in addition, you want Vim not to do its usual
when you press 1 followed by s (which is the same as s i.e. delete the
character at the cursor and start Insert mode) you will have to define
an additional mapping to override that:

:nnoremap s1 :echomsg "Hello world"<CR>
:nnoremap 1s <Nop>
