Question

“There are basically two types of people. People who accomplish things and people who claim to have accomplish things. the first group is less crowded.” Explain Mark Twain’s point.

Answer 1

Mark Twain's point is stating that there are two types of people, people who do their work and people who take credit for others work. He states that the first group is less crowded because more people take other peoples work and say it's theirs.

This might not be the answer you're looking for but to put it short, he's saying more people take credit than put any out there.
