I was repairing some landscaping lighting, and when I took the cover off

wiring connections, held together by wire nuts, or maybe it did.

How did the water get in?

Because if it had, the breaker would have tripped, right?

Only if it had a GFCI and the water caused current flow in the ground
wire.
