Excuse me for not quite understanding what he’s trying to say.
I doubt he does either.
He’s saying that inflation is a good thing in this case because it means we’re taking out their ships.
You’re in good company. My wild guess is that he’s trying to say inflation’s transient, but that’s what every administration (including the last one) says when the numbers suck. And “I love the inflation” is probably the worst way to express that thought.
I doubt he knows either at this point
“Excuse me for not quite understanding what he’s trying to say.”
Me too, but underneath the bluster I think he and his team knows what they’re doing, and being ambiguous or incomprehensible is part of the strategy — maybe. We’ll see.

Let me try... I speak "Trump."
President Trump is speaking from the perspective that oil was recently at $100+ per barrel. When Trump said:
Do you know we’ve been taking out millions of barrels of oil? Nobody knows it. You know who doesn’t know about it? Iran — until right now. We took out, the other night, 22 ships, late at night, with no lights, because they don’t have any radar, because we blasted the crap out of it... We took it, that’s why oil is $85 a barrel.
Trump was pointing out that oil dropped to $85/bbl because of the recent covert military operation that flooded the market with oil, keeping inflation to just 4.2%.
Trump is treating the inflation metric as a de facto battlefield damage assessment, not just an economic statistic when you consider the following:
Oil dropped to a low of $85.95 on June 8, which is the source of Trump's "$85 a barrel" quote. He's saying that inflation have been even higher if our military hadn't been able to covertly sneak the oil tankers out of the Strait, which led to resupply of the global oil market that is keeping inflation contained until the Strait of Hormuz reopens and oil begins flowing freely again.
