I think that the quote means if you don't get to see art, then you won't become an artist. I think that you can still become an artist if you don't see art but it is much more difficult. In my picture I have drawn someone who lives in a developing country and in a small village with no towns nearby. This person wouldn't be able to go to museums or theatres because they don't live anywhere near those places and they don't have the money to travel to them. So they won't see much or any art and that would make it difficult for them to become an artist. But the people at the bottom of the picture are people like me who can go to places like cinemas (on the left in the picture) and most people have internet access at home which means that they can go onto free museum and gallery tours (on the right in the picture). And we might be able to watch plays on Youtube so even if we can't go to the theatre we can still see art. We can easily see lots of art and that makes it mush easier for us to become artists. I think that is what the quote is about.
