Not sure what you mean by illegal trash dumping. Trash that's dumped directly on the coast and not into a river first?
Trash that's illegally dumped off shore. It's harder to dump large amounts of trash in a river and not have somebody notice - it's easier to say you're transporting it and "lose" part/all of it while at sea.
I'm not an expert and I'm not that interested in arguing specific numbers - I have no emotional attachment to them. The article being discussed here disputes your claim.
A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers [...] The 10 rivers that carry 93 percent of that trash [...], so 10 rivers are said to contribute 25% of total trash and 93% of river-trash. That'd leave ~68% from the shore, which sounds very high.

Shipping waste is 5% of plastic in the ocean.
85% comes from either rivers or shorelines.
