The real estate mogul said it was "horrific being judged by everybody" because normally she’s the one doing the judging.
"It’s so much better to be a judge and tell everybody they're terrible," Corcoran, 68, said on "Good Morning America" after her elimination. "I thought I was fabulous, but nobody agreed with me."
She said the "DWTS" judges were "totally fair" and she "can’t argue" with their decision.
"I don’t like the results, but they are what they are," Corcoran quipped. "I’m used to coming in first."
She also said her professional partner, Keo Motsepe, was "distracting" when he’d sweat during their dances.
"I tried to put my clothes on all the time," Motsepe said with a laugh.
Corcoran’s "Shark Tank" co-star Kevin O'Leary surprised her in the "GMA" studio, joking that he was the only Shark that believed in her.
"I wanted you to go all the way," he said before teasing her about her elimination.
"Barbara, you were spectacular," O’Leary began. "I wish I could be there tonight to watch you. But, oh, you’re not there anymore."
In jeopardy at the end of the show were Terrell Owens and Cheryl Burke, an announcement that drew boos, and Corcoran and Motsepe. Both were at the bottom of last week’s leaderboard.
