Casinos are the most affected in this pandemic because social distance is an impediment to providing their services in full and are now limited. The Covid19 can be presented even following the strictest controls because a small error could open the door and infect anyone. We can only take advantage of bets on games that can be carried out with a lot of effort today.
Trying to count who is most affected by the pandemic is not quite correct. You don't need to think long to understand that the entire service sector, designed for visiting people, has suffered large losses. Some managed to minimize losses, some were helped by the state, some went bankrupt, and so on. Now it is better to think about how to recover. And do you think it is possible to start holding mass events, opening casinos and restaurants?
