I mean yes thats true, but you also have to look at the capacity to renew what they are using to fight the war.
Iran appears to have a large supply of drones, enough to overwhelm US defences. Each drone is ~$50k and takes a few weeks to build, the anti-dorne missle (depending on what one it is) costs $4m and take longer.
If trump does decide to take Kharg island, then to stop the troops from being slamai sliced they'll need an efficient, cheap anti drone system, which I don't think the US has (apart from the Phalanx, but there arent enough of those)
To stop the drone threat, they'd have to clear roughly a 1500km circle. no small feat.
the bigger issue is that the goal if this war is poorly defined. It was supposedly to do a hit and run, and gain a captive client. Had they listened to any of the intelligence, rather than the ego, they would have known this would have happened. that has failed, now what, what do they need to achieve? There is no point committing troops if they are there for show. (there was no real point in this war either, well for the US at least.)
