Hi Robin!
As you mentioned that you have completed diploma in 2019 and got admission in college by lateral entry, so I am considering that you got admission by diploma score, not by 12th scores. In this case, your gap will be considered of 2 years which you take after 10th class ( completed 10th in 2014 and got admission in diploma in 2016).
Hope I answered your query, thankyou!
