ELI5: Why does combining heavy turning and braking cause a car to understeer and wipe out?

I've wondered this whenever I screw up my gameplay in Asseto Corsa, Forza Horizon 4, or Gran Turismo 4, causing me to spin into a wall.

Tires only have so much grip  before they slip.
Let's say your tires have only TEN "grips" to give before they slip.
Speed, takes away some "grips', turning takes some away and braking too. They all take.
So if your speed into a corner takes 6 grips and your braking takes 3 grips But your steering takes away 4 more... thats 13 grips! 
You've taken all your grip away and you will slide.
To make that corner you have to give away 
less of your grip by steering less, braking less or slowing down.
