The cable with the white wire that's connected to the two black wires is a switch loop:
Normally wires with white insulation are used only for neutrals, but code makes an exception to allow for use of the white wire in a cable used as a switch loop as a hot rather than a neutral.

That is positional coding. It is very important data.
Wire colors in cable are standardized and do not vary. In any cable, if neutral is present, it must be the white. The most likely application for this is in a switch loop. If neutral is not present but an always-hot is, contemporary Code says white must be used for an always-hot. That's to make it easier to identify with a voltage tester. Newer code says white so used, must be marked with tape.
Once you have identified the neutral bundle (all white), a white in a non-neutral bundle is one of these. The fact this is in a lamp makes this most likely a switch loop.
Most likely its partner black is the switched-hot. The lamp will want this switched-hot, and actual neutral.
