While Wikipedia (especially the English version) has its problems. That statement is an exaggeration.

You're very likely to run into these issues if you contribute to certain topics. Examples include living persons, video game characters, some piece of software you wrote, or anything else that's not very notable, controversial or hard to find references for.

However for the vast majority of topics this isn't an issue. If you're just writing about a place, landmark, some historical character, a scientific discipline or any of the topics that make up ~80% of the actual content on Wikipedia you're not going to have your article listed for deletion.
