> I got the impression that I could continue riding to Amsterdam in the same fashion if wanted to.

You definitely could. A couple of years ago I've actually done a trip like that, Rotterdam to The Hague to Amsterdam (then onwards to Amersfoort) — it was about 150 km long, and all of that was on designated bike paths and lanes.

That sounds like a nice trip. Yeah the bike paths between Rotterdam and Delft were particularly memorable, you were basically biking through open farm land following a canal. It was like riding through a postcard. Cheers.
