Gather and pile up both end with things together, but they differ in order and feel. Gather is the neutral act of bringing scattered things into one place — leaves, papers, a crowd. Pile up is informal and usually unwelcome, the disorderly heaping of things to excess — dishes, debts and work pile up, faster than we deal with them. Gather is the tidy bringing-together; pile up is the dreaded, messy heaping.
Both assemble a quantity, so 'leaves gathered by the gate' and 'leaves piled up by the gate' can describe the same corner — but the mood differs. Gather, from gaderian, is the plain bring-together, with no judgement: you gather what is spread out into one place. Pile up is the colloquial verb for a heap that grows disorderly and is usually a burden: it mounts past comfort and you wish it away. So volunteers gather the litter (purposeful, tidy), while rubbish piles up when no one collects it (unwanted, messy). Both make a heap; one is brought, the other dreaded.
gather
To gather is to bring scattered things together into one place — leaves into a heap, papers off a desk, a crowd into a square. It is the plainest, most general member of its family: where you collect by careful selection and things accumulate almost on their own, you simply gather whatever is spread out and draw it in. From the Old English gaderian, 'to bring together', it serves the concrete (gather wood) and the abstract alike (gather evidence, gather your thoughts).
pile up
To pile up is to accumulate into a heap — and, more often than not, an unwelcome one. It is the informal, faintly dreading cousin of accumulate: dishes, laundry, debts, unanswered emails and traffic all pile up, usually faster than we deal with them. The phrasal verb carries a sense of disorder and excess — of things mounting past the point of comfort — which is why the noun 'pile-up' can mean a motorway crash as readily as a backlog of work.

Both make a heap — the split is tidy/neutral vs messy/dreaded. Gather is the rake: scattered things brought together on purpose, no judgement (gather leaves, gather a crowd). Pile up is the sink of dishes: a disorderly heap that mounts unwanted (work piles up, dishes pile up). If you are bringing the scattered together, you gather it; if it is heaping up messy and unwelcome, it piles up. Tip: you gather the leaves; if you never do, they pile up.

They meet at the heap — leaves can be gathered or pile up — but gather implies someone brought them together tidily, while pile up implies they mounted on their own, unwanted and messy. You gather on purpose; things pile up on you. Swap them and a chore becomes either a task done or a mess dreaded.
