Duda began his football career at his hometown club MFK Snina. He later moved to MFK Košice, where he rose through the youth team ranks, making his first-team debut for the club at the age of 17 as a late substitute during a 1–0 home win against ŠK Slovan Bratislava.
In the winter of 2013-2014, Duda decided to not extend his contract with Košice, which would expire the following summer. In February 2014, Duda then joined Legia Warsaw on a four-and-a-half year deal.
On 30 July 2015, Duda was hit by a stone in Legia's UEFA Europa League qualifier away at FK Kukesi in Albania, being stretchered off and the match abandoned. The game was awarded as a 3–0 Legia victory and their opponents were fined £49,160 and forced to play their next European home match behind closed doors.
On 20 July 2016, Duda signed for Bundesliga side Hertha BSC on a five-year deal. After being sidelined with a knee injury shortly after signing and also undergoing a knee operation in November 2016, Duda made his competitive debut for Hertha on 25 February 2017 in a 2-0 win over Eintracht Frankfurt as an 89th-minute substitute, 7 months after signing with the club.
Duda experienced a good season with Hertha in 2018–2019 season. He played in 32 of the 34 Bundesliga games, scoring 11 goals and adding 6 assists. Even though Hertha had failed to qualify for any European competitions in the subsequent season, finishin 11th and 11 points behind Europa League positions, Duda was spotted and inquired about by Sevilla, as reported in mid-May 2019. Sevilla was to send an offer to Berlin, even meeting with Duda's father.
