Generally, the question is why/should VID fluctuates so much and if this means anything.
I'm new to this scene, I was never into overclocking before.
I have the AORUS Z370 Gaming 7 motherboard and overclocked my lidded i7 8700k to 4.8ghz [4.5ghz Uncore, TurboBoost Enabled] in the BIOS with default voltage settings, because this was recommended by both the manufacturer and online tips for doing "lower" overclocks (like 4.7-4.8ghz) which the unlocked 8700k CPU should be sufficient to handle. I originally used Intel Extreme Tuning Utility, but it started giving me unstable overclocking after two weeks of use with no issues (it losing frequency under load intermittently by ~100mhz), and I've read to simply set to defaults, uninstall, and overclock from BIOS. It's running at a steady 4800mhz now under variable load. (Yes, temps are fine, I'm just concerned with power and frequency at this point)
The VID is constantly moving randomly between 1.26-1.38V even at 0-3% CPU usage. I'm using CoreTemp to monitor VID, Temp, Usage, and Clock, but I ran HWiNFO64 and noticed an even more, quicker fluctuation (down to 1.20V) with HWiNFO64. I'm assuming that just has to do with a different sensor and refresh rate.
Everywhere I read claims that they overclocked their CPU with something like "1.34V stable", and I was wondering what this means exactly and if it's normal for your VID to fluctuate like crazy. If so, what is the point of changing your voltages in the BIOS the first place if they simply dance all over the place? I've read that for the longevity of your CPU, you don't want to go over 1.4V, but I don't seem to understand how this is controlled. I used the "Intel Burn Test 2.54" which artificially put the cores at 100% and it was running at 1.3302V pretty steadily, but it goes higher occasionally in real world use (haven't seen it over 1.38 yet).
I don't want to damage anything and I'd like to maximize the performance I get with overclocked frequencies. I couldn't find a lot of solid information on how this all works, with a lot of conflicting or incomplete information. despite my efforts. Maybe in the future I'd want to [see if I could] go over 4.8ghz, but I'm content with it right now.
I might be overreacting and looking for a reason as to why my overclocking randomly stopped working despite having no hardware/software changes, but I also just want to know for sure my CPU is working alright and won't become damaged.

You helped me figure out the VID versus Vcore - I hadn't yet seen information clarifying the distinction between them. 
I figured out Vcore has to do with the motherboard, and using HWiNFO64 Sensor Status, I was able to see my Vcore peak at 1.320V with stress testing at 4.8ghz with default voltage settings. With this information, I can much more easily investigate and understand the situation. Now I know why and how I can manually tweak the voltage, and why my VID was fluctuating all over the place. There are so many settings that have to do with voltage but they're all different... 
I've noticed that there's a lot of trial and error that comes with overclocking, and even some crashing when you push your hardware too far, but now I can deal with that effectively, thanks for the response!
