Basically it is.
If Trump reallly did anything for the economy, we should be able to cite the policies that made the difference. Effectively, the only one that made a huge difference was the tax cuts. Without it, growth would have been lower than Obama 2014-2016. Those tax cuts had an effect very much like a crude, old fashioned stimulus bill.
Stimulus is often done by the government borrowing more money and spending it, taxes don't change so the public spends the same, and so the additional government spending on top of normal government and public economic activity means more economic activity in total, at the cost of the national debt going up. What Trump did here was that he cut taxes so the people had more money to spend/invest, and the government spent the same, so in total there was more economic activity. At the cost of the national debt going up.
So that's the Trump economic "miracle" in brief: boosting the economy through more government borrowing and national debt. That's national debt's got to be paid back eventually, but that's someone else's problem, isn't it?
Okay, precisely, Obama said there were
manufactuing jobs that were never coming back without a magic wand. So here's a graph of manufacturing jobs 1999-2018.

Around 17-18 million in 2000. ~14 million at the end of GWB and the crash. And under Trump by 2018, still under 13 million, well below 2008 levels. Incidentally, net manufacturing job creation in 2019 was very low.
So no, he hasn't really brought those jobs back, either.
And just to ram the point home, here's the US trade deficit:

So Trump oversaw a record trade deficit as well, underlining the point of how little the USA was really producing of its own under his presidency.
