No. It's actually inherently true of any free exchange between two parties. Because both sides were happy to trade, and made the effort to do so, it's a benefit to both parties to trade in this way, which makes it a non-zero sum game. This is the core of why capitalism actually produces wealth, but socialism cannot.

The above is just completely wrong, but these are common misconceptions.
First, capitalism works
because there are limited resources. In fact, resources being unlimited is one of the only ways SciFi has escaped capitalism (Star Trek), and even then it comes back somewhat. In fact, a free market is how best to allocate a limited resource, as it's basically a massive computer that outputs the answer as a price and who's offering that price. More, that price tells people what resources are becoming limited, and when to look for more or an alternative.
Second, comparative advantage (the ide free trade is based on) very much
doesn't require that each country excels. Just that their rates of production are in different ratios. One country can actually be better at everything than the other country, and it's still worth trading.
Here's an example, let's cut the Economy into two goods, minerals and machines. Uganda takes 1 day to make a mineral, and 1 week to make a machine. The US can produce at a mineral in half a day, or a machine in one day.
The US could earn 3 mineral and 3 machine by taking 4.5 days doing it themselves. And it would take Uganda 8 days to just get to 1 mineral and 1 machine. Or they could trade. The US offers to trade a machine for 3 mineral. Uganda accepts. It save the US a half day/ work, and Uganda 4 days
| Time to produce alone | Time to produce with trade (1 machine = 3 mineral) |
US | 3 * .5 + 3 * 1 = 4.5 days | 4 * 1 = 4 days |
Uganda | 1 * 1 + 1 * 7 = 8 days | 1 * 4 = 4 days |
Basically, you don't actually need to excel. You just need to produce in a different time ratio to make trade profitable.
The above is the math behind why free trade works. Now there are actual issues with free trade, but not any of the ones you listed. They aren't really economic issues, mostly they are power/politics issues. The big ones are the following: first, benefiting an enemy. The issue with free trade with China is that you've empowered a geopolitical enemy. That's not an economic issue though, that's a power/politics issue. More, China's flouting of intellectual property has made other issues of free trade as well. Then there's the moving of jobs, a classic politics issue. And I could go on.
