Phenol is more acidic than ethanol. In phenol O-OH group forms bond with benzene ring and in ethanol it forms bond with alkyl group. Phenol have a more stabalised Phenoxide ion because of rasonance than the alkoxide ion in ethanol. So phenol proceed forward reaction being more reactive and acidic.

The difference is that , in Phenol, The OH group is bonded to a benzene ring whereas in Ethanol it is bonded to an alkyl group.
Impact of structure on The acidity:
on Phenol:The lone pair of electrons on oxygen delocalises into the Benzene ring (mesomeric effect) which reduced electron density in the O-H bond. The O-H bonds is weaker and therefore breaks easily in comparison with ethanol.
On Ethanol: The electron releasing inductive effect of the alkyl group increases electron density in the O-H bond. This strengthens the bond so the bond breaks less easily.

Ethanol is not acidic enogh to form salts with NaOH but phenol will.
