You misunderstand the trap that is poverty. Uber isn't "allowing them to make money in bad conditions". Uber has become the condition. There is no getting out of being a Uber driver when your day is spent driving around. No ability to look for other employment related to what you were doing, no ability to get training for another job. Uber thrives on misery.

So, yes, pôle emploi is a better option for many. Note that driving an Uber doesn't even get you qualified for unemployment later on, should you want to stop.
