Yes.

but in the case of wire the insulation has a lower melting point than on a
PCB(which is due to the type of material and the size?)?

Technically, the insulation has a maximum safe temperature, and your
PCB has a maximum safe temperature, with "safe" defined accordingly
for each. Your project could have a different and unique definition
of "safe" for example. Enclosure temp, thermal cooling of other
components, heatsinks, etc.

But in general, you can't use the current ratings of wires as a guide
to the current ratings of traces.
