Villa made her senior debut at the 1st Italian Serie A competition.
 She finished first in the team and all-around and scored highest on balance beam and second highest on vault, behind Alice D'Amato.
 She was slated to make her senior international debut at the 2019 City of Jesolo Trophy but had to withdraw at the last minute due to an injury to the middle finger of the right hand.
 It was later revealed that she broke her finger and would therefore have limited training leading up to the 2019 European Championships in April.
 In late March Villa competed at the 2nd Italian Serie A, but she only competed on uneven bars where she recorded the highest score.

In April Villa was officially named to the team to compete at the 2019 European Championships alongside Iorio and the D'Amato twins.
 Villa qualified to the all-around final in seventh place after falling off the uneven bars and qualified to the balance beam final in first.
In the all-around final she managed sixth after making mistakes on bars and floor and falling on beam, and in the balance beam final another fall took her out of medal contention.

In May Villa competed at the 3rd Italian Serie A where she placed first in the all-around and on vault, uneven bars, and balance beam.
 In August Villa competed at the Heerenveen Friendly where she helped Italy win gold in the team competition ahead of the Netherlands and Norway and individually she won gold in the all-around despite falling on the uneven bars, finishing ahead of Eythora Thorsdottir.
 Additionally she recorded the highest balance beam score and the second highest vault and floor exercise scores.
 On September 4 Villa was named to the team to compete at the 2019 World Championships in Stuttgart, Germany alongside Alice D'Amato, Asia D'Amato, Elisa Iorio, and Desirée Carofiglio.

During qualifications at the World Championships Villa helped Italy qualify to the team final in eighth place; as a result Italy also qualified to the 2020 Olympic Games in Tokyo.
 Individually she qualified to the all-around final in twelfth place.
In the team final, Villa competed on all four events to lead Italy to a surprise bronze medal – Italy's first team medal since the 1950 World Artistic Gymnastics Championships.
They ended up finishing behind the United States, winning their fifth consecutive title, and Russia but finished ahead of China, who originally qualified to the final in second place.
 During the all-around Villa finished in sixteenth place after falling off of the balance beam.
 She received the fourth highest score on vault behind Simone Biles of the United States, Aline Friess of France, and Giulia Steingruber of Switzerland and the fifth highest score on uneven bars behind Nina Derwael of Belgium, Elisabeth Seitz of Germany, Biles, and Tang Xijing of China.
