Does karma force things to happen?
It doesn't force things to happen because karma by definition has no self which can force anything.
Karma doesn't really exist as some punishing entity (like a Western God), which is what the word "force" implies in your question.

In Buddhism and Hinduism, the chain of causation that binds beings to the Wheel of Birth and the natural conditions that stem from it, creates a torrent of karma all of which must be satisfied in life after life until samadhi/bodhi can be achieved.

"Conditions" can be anything by the way. A condition can be being in a certain situation, seeing a certain characteristic of a person (e.g. maleness, femaleness), or even "having a body". Oftentimes I believe that karma has an effect that is beyond time, simultaneously immediate, near, and far..
