Gastelum is of Mexican descent. His family is from Ciudad Obregón, Sonora, where he lived temporarily during his childhood. Gastelum won a 5A Division II AIA state wrestling title out of Cibola High School and continued to wrestle at North Idaho College, where he was ranked as high as fifth in the country (NJCAA) as a freshman before deciding to compete in mixed martial arts professionally. He worked as a bail bondsman prior to training MMA full-time.

After turning professional, Gastelum amassed an undefeated record of five wins (all finishes) and no losses before competing in The Ultimate Fighter.

In January 2013, it was announced that Gastelum was selected for The Ultimate Fighter: Team Jones vs. Team Sonnen. To get into the TUF house, Gastelum defeated Kito Andrews by decision. During the choosing of teams, he was picked last by coach Chael Sonnen for Team Sonnen.

Gastelum is known for his compact southpaw boxing style, blending quick hand speed with forward pressure and durability. Despite often being the shorter fighter in his weight class, he uses head movement and tight combinations to close the distance and force exchanges in the pocket. He often relies on counter left hands and looping hooks during exchanges, and his ability to absorb shots and fire back has made him a dangerous opponent in back-and-forth fights.

While primarily a striker, Gastelum has a strong wrestling background from his collegiate days and occasionally uses it to keep opponents guessing. However, he generally prefers to keep the fight standing, using sprawls and lateral movement rather than prolonged grappling sequences. His style has evolved over the years to emphasize explosiveness in short bursts, and he often thrives in chaotic exchanges where timing and toughness become deciding factors.
