As far as I can tell it's been three months since you decided you wanted to "learn networking", you've posted five threads since then essentially asking people to feed you learning on certain topics, not contributed to threads outside of ones you started yourself, you've tried to learn about switching, routers, virtual machines, active directory, none of your questions say "here's the material I've been learning from, I have x question about y section". No wonder you're confused, you seem to have no structure to your learning - you can't just watch YouTube videos about fifteen different topics and then make a sadface post when you don't pick it up.
Learning this stuff in theory doesn't count for anything. Nobody will give you a job because you can explain how packets get from A to B because that by itself isn't a hugely valuable skill. If you want to get into the industry then you need an entry-level job which will likely be on a support desk somewhere or a field engineer, and you learn from that point. None of those jobs will need a packet/frame level understanding of a computer network, and spending a year getting a CCNA is pointless because I'd be sceptical of someone with one and no experience.
Get an A+ if you can't find somewhere that will train you or can't take the wage cut, I highly recommend something instructor led because it doesn't seem like your strategy for self-paced learning is really working out for you. You also don't need to know how things work at a low level, you just need to know how to use the tools that exist. Can I diagnose that packet loss exists on a link and change a cable/clean a fibre/swap an optic/diagnose the interface as faulty to get the problem solved? Sure I can. Could I tell you why it's acting up if you gave me a scope? Not a chance, I don't need to know either and I don't let it bother me. Cables are cheap, time is not, swap it out and get on with your day.
