"Think of it like a dice roll: You either roll or 6, or you don't, so basically it's 50/50."

Brazilian Portuguese speakers change 't' and 'd' to 'ch' and 'j' respectively before 'i' and 'e' sounds. For example, the word 'de' meaning 'of/from' is pronounced more like 'juh'.

This happened in Japanese too, where the original "ti, tya, tyo" became "chi, cha, cho"! These are all types of palatalisation, which is one of the most common types of sound change across languages.

Dr Geoff Lindsey has a fantastic video on the related phenomenon of why the in statue is pronounced like a "ch" and why English people pronounce tube as *"choob"
