Myth or truth?

"I can learn English from a teacher whose native language is the same as mine. This means if my mother tongue is Hindi or Tamil, I can learn English only from a teacher who speaks that language."
Is this true or just a myth?
Take my opinion; the statement is false. I have taught Beginner’s level students from different parts of the world, each having a different native language. I have been using rich multimedia content full of explanatory images, audio and video inputs that simplify the learning process.
Indeed, as a teacher, I get to learn and innovate much more when the common language between the student and me is just English. Imagine what an experience it is to teach the use of basics like ‘is’, ‘am’ or ‘are’ to learners who are new to the English language.
Finally, it is the mindset that matters. After all, aren’t we prepared to master a new language, say French from any teacher who knows the language properly? To me, it won’t matter if s/he knew English or my native language Hindi?
What do you think?
