What percentage of unicorns are profitable?

Could you please elaborate on the profitability of unicorns? I'm curious to know what percentage of these startups, which are often highly valued and receive significant funding, are actually turning a profit. Is it a common occurrence, or is profitability among unicorns a rarity? Additionally, are there any notable trends or factors that contribute to the profitability or lack thereof among these companies? Understanding the financial health of unicorns could provide valuable insights into the broader startup ecosystem.
