No... you may feel tired from lack of sleep, lack of vitamins, lack of nutrition, anxiety, worrying, stress and sometimes even from doing any form of physical activity.
If you feel tired and can't focus after getting to sleep after 12 pm. you probably did not get enough sleep. If you are dizzy, it could be due to lack of sleep, but it might also be due to other factors.
