Also
how ‘luck’ works in a closed world system, is that, if all things are defined as equal,
Then this would suggest that the bad luck should be dumped to those around you.
While you experience the good. A measure for measure.
If you found 20 dollars
means also somebody lost 20 dollars.
The difference in these, is that it is burned/converted like in crucible, to produce a state where it doesn’t rely on the bad luck of others to fuel your good luck.
The horseshoe and clover, 777 etc. work a lot differently
as the concept of this kind of luck is a larger mass of ideas defined by people over the hundreds of years using it.
Doesn’t work quite the same way as an ‘exchange’ good for bad.
They work more along the lines of a unwavering faith or belief that can help ‘redesign’ your personal reality/environment.
like a symbol (the horseshoe, the clover) representing this mass created potential.
777 being more focused on ‘alignment’ a subset of the main flow of reality.
In this state, things ‘flow’ naturally and align for success in a sense a more tailored probability alteration.
So no,
Does more luck = more Bad luck?
it doesn’t do that 
Or in the way you thought.
