Richarlison says Brazil's players "will do everything" they can to win a record-extending sixth World Cup in Qatar.
Brazil are steeped in World Cup history, with more titles than any other country, though their fifth and most recent triumph came in 2002.
Tite's men head into the tournament in Qatar as one of the favourites having lost just one match since 2019, their Copa America final defeat to Argentina last year.
Richarlison will be playing in his first World Cup, having scored 17 goals in his 38 appearances for the Selecao since his debut in 2018.
The 25-year-old says he and his team-mates will do all they can to bring home the trophy, telling Eurosport: "If we will win? I don't know, but we will do everything to win the World Cup.
"I prefer that we work in silence, doing our job and doing our best every day. Certainly, Professor Tite [head coach] will prepare us well for a great World Cup."
The Tottenham forward believes Brazil deserve to be among the most fancied teams and is confident they will make an impression in Qatar, saying: "I think there are a lot of good teams, but we are Brazil.
"We have a lot of history, we've never been out of the World Cup and we're going to the World Cup to honour the shirt. We're definitely going to get something good for us."
Despite his belief in Brazil's prospects, Richarlison acknowledged other sides he feels have a chance, adding: "There are a lot of good teams.
"The defending champions, France. Belgium, for example, and Argentina, which has a good squad and won the Copa America."
Brazil open their World Cup campaign against Serbia on Thursday, before facing Switzerland and Cameroon in Group G.
