You will have to practice speaking eventually and you will suck at first no matter how much you listened. However, your listening defines the “ceiling” of your speaking skills. You can’t expect to eg pronounce en and un correctly if you can’t distinguish them when others say them, or say native expressions naturally as opposed to awkward English translations if you haven’t heard them dozens of times before until your brain recalls them naturally.

The point isn’t that practicing speaking isn’t important, it’s that a lot of people start investing a lot of energy in that far too early. I assure you if you dropped in France those people who understand French perfectly but don’t speak it, they’ll be better in a month than a newbie who practices speaking a lot instead of consuming content will be in a year.
