Isn’t one OLTP and the other OLAP? I don’t understand why DuckDB is often suggested as a drop-in replacement.

Yes, DuckDB is OLAP, SQLite is OLTP. I should have called that out.

But if you are doing aggregate or skip-scan analysis and if they're talking about read speeds and in-memory processing, well, SQLite leaves some performance on the table by being single-threaded, as far as I can tell.
