That’s what I guessed 
but didn’t want to assume.
Unfortunately, I am not familiar with the schooling system there to assess the relative strength of your academic profile but other posters might be able to comment.
It’s very important you have this conversation with them. Education in America is very expensive. The cost of attendance at UChicago for example, is about $90,000 per year. $376,000 over 4 years assuming a modest 3% annual increase. And that does not include the cost of your flights back and forth from your home country. So please ask them explicitly if they are willing and able to pay this amount. If yes, that’s great news (and you can always seek merit $$ if available, to reduce their cost). If not, you will need to find schools that will provide sufficient financial aid to international students like you.
So, have that conversation and let us know.
