If I have a deficit, how come I’m not broke?
It’s probably a timing issue.
This year’s losses might be floated by money that you made in the past.
Or perhaps next year’s money has started to arrive. This is common for performing arts companies that sell seasons on subscription: in the spring, when next year’s tickets go on sale, money arrives that might make you feel flush, but that actually should be carefully stewarded so it can be used to pay for the next season. In the same way, grant instalments might arrive early.
Perhaps the bank is in good shape despite your losses because you haven’t paid the bills yet. You may know that you’ve lost money, but still be awaiting invoices from suppliers.
