Can I interpret the sentence as "high risk and high return"?

That seems to be a good way to put it! These court cases are challenging (cases are hard), and there is a lot of money that they could lose if they don't win these cases (stakes are high). You may already know this, but "high stakes" means a situation where a lot of money or something extremely important is at risk. If they win these difficult cases (high risk), they will receive a lot of money (high return).
