The examples you gave are in m/d/y format though, and DATEVALUE() parses your examples correctly into Jan 15th, 2024 and January 3rd, 2024.
DATEVALUE() parses ambiguous short date formats (e.g. 1/3/24) using the short date format specified in the Region settings of Windows Control Panel. So if you want to parse d/m/y format, you can try changing the settings there.
