Yes. Not only do they get a 'cost of living' stipend (a few thousand dollars), but they get other money in a lot of other ways as well.
Their scholarship includes room & board. At UNL room & board is $11,430. However if they live off campus, then they get a check cut for the total amount of room & board. Players usually live in houses together so say they live in Lincoln year round for $500 rent/utilities, that's $6,000. That means the player has $5,430 left over that's just theirs.
There's also the Student Assistance Fund, which provides players money for things they need but aren't covered under a scholarship - flights home, child care costs, summer school, graduate test fees, etc. And they get several hundred dollars to purchase non-athletic clothing such as suits.
None of that goes into the non-monetary value of professional world class strength and conditioning, nutrition, tutoring, life skill training, physical therapy, opportunity to travel, bowl game gifts, clothing, publicity, and so on.
Oh, and now players are allowed to get paid actual money for their own likeness as well.
