What does 'Up to 500,000 copies/views of the asset' mean?

I see that it says in the licenses for standard, enhanced, and extended that unlimited web views are a thing. I'm assuming this accounts for Youtube and social media.  The thing that perplexes me though, are the 500,000 copies in the standard license. Does this mean physical, because if it does then why does the extended license specifically go over merchandise and products for resale? If the extended license is talking about merchandise, then what are the 500,000 copies referring to exactly? Also if I wasn't planning on selling merchandise,  then does that mean a standard license would be enough if I just wanted to make a video for people to see? Could I charge a toll or something, so people could pay me to see the video online with a standard license?
