Selenium Web Browser Automation

Manual QA here want to start learning Test Automation. Coming from a non-tech background will make it a bit of a challenge but I'm looking to "test" myself.

Out of the three languages (Java, JS, Py), which should I focus on learning to get the best knowledge to apply when eventually using Selenium WebDriver?

I would like to comprehend all three later on in the future but for now which is the best to start off or continue with. Many have mentioned Python is beginner-friendly approach to learning programming and less stressful, but I see a lot of tutorials for Selenium webdriver being taught using Java, Also I heard JS is being implemented a lot more and more nowadays.
