Hint: Endothermic are reactions where chemical energy is absorbed from the environment. For example: melting of ice cubes, evaporation of water, etc. Exothermic are reactions where energy is released in the form of heat into the environment. Example: burning sugar, mixing water and strong acid, etc.

Complete answer:
Cations are the ones that lose electrons to gain a positive charge. Mostly all metals are cations. During electrolysis, they move towards the cathode. Examples-\[N{a^ + },{K^ + }\]
Anions are the ones that accept electrons and gain a negative charge. Mostly nonmetals can be considered anions. During electrolysis, they move towards the anode. Example-$C{l^ - },B{r^ - }$
When losing an electron heat and energy is required so you supply heat and energy to the metal ions and then it loses an electron and gains a positive charge. Whereas when there is acceptance of electrons one needs there is a release of heat and energy so non-metals release heat and energy whenever they accept an electron and gain a negative charge.
Hence because of the above cases, we can say that formation of cations is endothermic and the formation of anions is exothermic.
Therefore the above statement is true.

Note:
The products formed during the endothermic reaction have more heat than the reactants. The energy released as the product during the exothermic reaction is greater than the energy required to break the bond in the reactions. The similarity between both the reactions is that they both involve redistribution of energy and they both have to do with energy and the bonds between the atoms.
