My advice would be to check out the popular Unity channels on YouTube. Examples include AdamCYounis, Brackeys, and BlackThornProd. These channels have plenty of tutorials on everything you can imagine. Make sure to make it along with them, not just copy but try to understand what you're doing and why. Eventually you'll reach a point where you understand the basic parts of development with Unity and you'll feel the unmatched sense of freedom and power of creation :)
