I am looking at the Zstandard library and it says that it is dual licensed, BSD and GPLv2. What does it mean? If I use libraries in a non open source program will the license be GPL or BSD?

In the source files I can see this text:

you may select either version 2 of the GNU General Public License ("GPL") or BSD license ("BSD").

Does this mean that I can use the code and just apply the BSD license to it?

As a user, you can elect to use either license, therefore you can pick the BSD license and ignore the GPL alright if you wish to do so.

Offering a choice of license is a somewhat common approach. And choice is good within reason, though it can be abused to absurd (or funny) levels, such as in this 8-way choice:

PYBLAKE2 IS OCTUPLE-LICENSED UNDER THE FOLLOWING LICENSES (choose one or several at your own discretion):
