I always found those analogies difficult to wrap my head around too, it always seems easier to understand small made big. Like enlarging an atom's nucleus to the size of a baseball or something and if you place it in the center of a football stadium the nearest electron would be in the parking lot. Or a human able to jump the height of a flea would be able to leap the empire state building. Or the amount an ant carries being the equivalent of you carrying around a Volkswagen.
I don't remember those analogies exactly but they're close enough. When it comes to big things scientific notation was good enough for me to get it. 10^14 as compared to 10^6, it's a massive difference that's hard to wrap my head around in some terms but I know how huge the difference is looking at the two numbers.
Maybe if I knew how many peas could fit in the sun it would be easier to visualize.
