for one, duckdb includes all of sqlite (and many other dependencies). it knows how to do things like efficiently query over parquet files in s3. it's expansive - a swiss army knife for working with data wherever it's at.
sqlite is a "self contained system" depending on no external software except c standard library for target os:
> A minimal build of SQLite requires just these routines from the standard C library:
> Most builds also use the system memory allocation routines:
> malloc(), realloc(), free()
> Default builds of SQLite contain appropriate VFS objects for talking to the underlying operating system, and those VFS objects will contain operating system calls such as open(), read(), write(), fsync(), and so forth

Quoting from the appropriately named https://sqlite.org/selfcontained.html
as a very rough and unfair estimate between the two project's source, sqlite is about 8% the size of duckdb:
