False.

Friction usually converts mechanical energy into internal energy (felt as heat), but it can also produce other forms such as sound (rubbing, squealing brakes), light (sparks, triboluminescence), or trigger chemical reactions (striking a match). Those nonthermal forms often later dissipate as heat, but friction does not always produce heat as the only immediate product.
