This hasn't been true since version 5.4.2, released in 2017.
`npm install` will always use the versions listed in package-lock.json unless your package.json has been edited to list newer versions than are present in package-lock.json.
The only difference with `npm ci` is that `npm ci` fails if the two are out of sync (and it deletes `node_modules` first).
IMO, `ci` should be `install`, `install` should be `update`.
Plus the install command is reused to add dependencies, that should be a separate command.
