There’s no way people learning spanish who are very good at it actually know/memorized all the conjugations?

As i’m learning, there’s like 7+ conjugations for every word that exists. How on earth do people memorize this? I’ve come to my sole conclusion that people don’t memorize these, but just start to grasp what to use based on the conversations they hear.

What is the best way your best way to memorize conjugations? Sometimes i know a conjugation 100% but don’t even use it because it doesn’t click in my brain.
