I think that for such a player, who has contracted tuberculosis, it is most likely not interesting to place bets alone, sitting in his apartment and actually being isolated from other people. 
It is true that for many players it is very important not just to place bets, but to discuss them with other people.  It is from such a discussion that, firstly, the decision on bets is made not only by the player himself, but also by a group of people with whom he discussed the bets.
Secondly, the player has someone with whom to discuss, one might say almost professionally, the bet that he is making.  This communication can be even more important for a person than winning or losing in the game itself. 
So this sick person is unlikely to be as comfortable and interested in gambling while sitting at home at the computer and alone.  This game probably won’t replace a physical casino for him.
