DiMarco and his pro partner, Peta Murgatroyd, spoke with ET's Cameron Mathison after the show, where the 27-year-old model explained, through his translator, that the win meant so much to him because he "really wanted to inspire."
It was clear how truly inspirational DiMarco has been after his cha cha/tango fusion dance during Tuesday’s finals which earned him a perfect score and left the audience in tears. During her feedback, judge Carrie Ann Inaba even thanks DiMarco in sign language.
"That was a beautiful way to end the season," Inaba gushed after the stunning routine. "But Nyle, I just want to say something to you. Because you've spoken to us so eloquently in our language of dance, I want to say this to you and I hope I get it right." Inaba then stood to speak to him in ASL.
"She said ‘Thank you,’ for sharing what's in my heart, and that's what really touched me because that's my goal every week," DiMarco explained to ET. "I really want to connect with the audience and teach them what it really means to be deaf."
During the emotional scene with Inaba, the soon-to-be-champ was brought to tears by her kind gesture, as was his mom, Donna, who cried with joy from the audience. DiMarco’s mother joined him after the show and opened up to ET about her reaction to Inaba's kind words and her son's tearful response.
"When he breaks down, it's so easy for mom to break down," Donna, who is also deaf, shared though her son's translator. "I just joined in on the emotion, and the emotional journey he was going through. He really deserves this."
DiMarco also opened up about his deep connection to Murgatroyd, who he repeatedly credited throughout the season for helping learn things about himself that he never knew and pushed him beyond what he thought he could accomplish.
"The first week that we worked together, she was already starting to learn my language and my culture. She was very curious. She did the right thing right out of the chute," he recounted. "It really was about learning about each other's worlds and I think that message was really strong."
After the win, DiMarco shared a picture to Instagram celebrating the victory, which he dedicated to the "70 million Deaf people in the world!"
"Thank you all for your CONTINUING SUPPORT. @petamurgatroyd YOU ARE AMAZING," DiMarco continued in the caption. "Thank you for embracing this journey with me. Thank you for pushing me and believing in me. I love you!"
On Monday, he posted a special message sharing his appreciation for the 29-year-old two-time DWTS champ, writing, "Peta Jane Murgatroyd, thank you is an understatement."
Peta Jane Murgatroyd, thank you is an understatement. There are so many things I want to express gratitude, but thank you for embracing the journey with me. Thank you for helping me tell my story through dancing: What it really means to be Deaf. Thank you for inspiring millions of [Deaf] lives with me. Last but not the least.., thank you for believing in me. Watch our finale dance to @disturbed's Sound of Silence tonight! VOTE: 1800 868 3409
Ultimately, it seems DiMarco -- who also won the final season of America's Next Top Model last year -- is most satisfied by learning to communicate through this new medium of movement, and what he was able to share with his fans.
"I was able to bring my upbringing out through our dance, [and] we were able to send out a message through dance," he explained. However, the model admitted he's "just sad that this has to end."
