Do people with incomes below 138% of FPL get subsidized ACA plans in non medicaid states

In a place like Texas that didn’t expand medicaid as part of the ACA If you make <138% federal poverty line can you qualify for subsidies for the ACA or do you not get anything until you are above 138%?

You get nothing.

However, if you miscalculate your income, and receive subsidies during a year in which you end up under the 138% line, you do not have to repay them.
