No, that's not correct. When he had Jimbo in 2013 (college) he was 40 TDs and 10 INTs.
With Koetter (TB OC and HC 2015-18) who is known for an aggressive vertical attack, it's understandable to see INTs. When Koetter went back to ATL last season, Ryan's TD/INT% got a lot worse. And Arians runs a similar O to Koetter (Air Coryell), so in short, Winston has had the same aggressive vertical system his entire NFL career.
In 2013 for example, unlike his days in TB, Jimbo used a ton of TE (O'Leary) and big possession Xs (6-5 K Benjamin) which translated into well rounded football. Add in a decent running game with Freeman, and a decent D, and bingo, 40/10.
