Well, no, high thermal energy increases the average energy of all collisions. Such is the definition of thermal energy. Yes, included in the average collision are outlying collisions where there might be excessive energy (you'll find water evaporates even at room temperature, just at a much slower rate), or a far lower collision energy, such as in the case above of U236 being produced instead of nuclear fission.

Reply to comment by iksbob in If nuclear fission in U-235 causes the atom to be split into 2 smaller atoms (such as Kr-92 and Ba-141) then how is it that U-236 is produced as waste since the U-235 was just split into smaller peices? by Ian98766
