Hoopgurlz does include international players in the ranking sometimes once they are pretty certain that the player is US college bound. The 2015 ranking had 2 European players in the top 5. Wouldn't be surprised to see Nika and Aliyah Edwards in the next Hoopgurlz update.
My guess is that Nika is a top 30ish prospect comparable to Kia Nurse who was 33.
A few int’l players and the rankings:

I missed a few I’m sure, please reply if you catch anything. So far, 2019 has not been a big year for internationals. Laeticia Amihere is the exception at #10.
These rankings are meh. Don’t give the best sense really.
