I had a couple of questions about the difference between the two the first one is
What's the actual term for pre cum?
The second one is
How come when I masturbate I only ejaculate a small amount of greyish clear thick liquid and how come it's not white or a bigger amount(I've taken this one with a grain of salt because my only knowledge of this is from porn and I am aware its very fake compared to actual sexual intercourse)
And three
What's the thin clear stuff that comes out sometime when I get aroused? It's the constituency of pee.

Okay, so here we go:

Semen is the fluid that (sparing people with conditions that change this for them) contains sperm cells and is released with a full ejaculation.
Pre-ejaculate (or "pre-cum") is a fluid that is usually also secreted by the penis, but often long before an ejaculation. All by itself it doesn't contain semen, and is though to occur in order to clear the urethra of old trace sperm cells and anything else so that if and when ejaculation occurs, it's all clear, basically. That's the stuff you're asking about that you see with arousal.

Gray-looking fluid from the genitals should generally be checked out by a healthcare provider. But maybe by grayish you mean it looks opaque but not bright white?

How much someone ejaculates varies, but no, the amount you often see in sexual entertainment isn't realistic and sometimes isn't even semen so much as water and cornstarch.

Ok that makes sense! It is just translucent white! And thank you!
