These experiences, though subtle, may have influenced his personal and moral framework, giving him a sense of discipline and respect for structure from an early age.

While Gamrot has not publicly discussed his personal religious beliefs, it is likely that he follows Catholicism, the dominant faith in Poland. Even as he focused heavily on wrestling and athletic pursuits, the cultural backdrop of his youth, with its emphasis on faith, family, and community, may have helped instill values that resonate in his professional life.
