Here are resources to get you properly started. If after overrides you aren't comfortable with tuning yet, you can try Mod Constructor V4 instead to make custom files, but it's not capable of doing everything and you may still need to edit files. Start small here otherwise you might overwhelm yourself. Then when you're comfortable at least reading some of the files and understand more of what you're doing, venture into making custom files. Start with overrides first, things that EA made that annoy you, such as changing the time it takes to do something, anything autonomous, etc. Almost all mods can be made in just XML (aka tuning), and is where you should focus first before venturing to scripting. You also don't need to do scripting majority of the time due to community tools that handle injecting for you, it's only when you require stuff that isn't covered. You don't need any skills unless you want to do scripting, and even then Python is easy enough to learn with outside resources, it's just that transferring that knowledge to Sims 4 is what's hard as it's not well documented.
