In 2017, over a million people[1] received legal permanent resident status. In 2017 it was slightly less than in 2016, but on roughly the same level as the previous decade. So recent policy changes don't seem to have much effect in that regard.
Over 500,000 of those are familial green cards (spouses and children), meaning they likely would have been issued regardless of the changes in policy and don't really reflect a multicultural dimension for the country.
Other permanent resident status issuances take up to 15 years to achieve, meaning you won't see the effects of recent policy changes in that metric until the years to come.
That depends a lot what exactly visas are those. There are dual intent visas, which allow change to permanent immigrant status, and ones that explicitly prohibit such change. Most visas at your link are B type visas, which would be denied if immigration officer even suspects you have intent to become a permanent resident.
