Is streaming and downloading the same amount of data on Netflix?

Or is less consumed when streaming?

Should be the same amount of data.

When streaming, the film is downloaded in exactly the same way as with a conventional download. The difference is that it is only saved temporarily when streaming. If you want to watch the film again, the same amount of data is generated again for the next stream. Otherwise, the amounts of data are the same.

Streaming means that the data would not stay on his PC.
