The recommended way to use OpenLayers is to work with the ol package. You can install the latest with npm:

npm install ol

If you want to try out OpenLayers without downloading anything, a full build of each release which can be used in a script tag is available from cdnjs. You will need both the JS build and the CSS files; see the examples or the Quickstart tutorial for usage. Note that you should not use a full build in production, instead you are encouraged to use the ol package described above.
