The days of bitcoin faucets being profitable or even worth the time are long gone I think.  I've never been a fan of them because the rewards are usually measly but requires a lot of time to keep clicking for claims.  Although it is worth noting that it's free and if one is patient with it over 6 months to a year, you might just be able collect a few thousand sats which in turn may be worth a considerable amount as the price of bitcoin keeps increasing.
To answer the question with a simple answer, I’d Say bitcoin faucets aren't useful now. Perhaps altcoins faucets might be a better bet.
