It can do, but usually does not.

Estimation
Yes, there is some uncertainty. Estimation is not an exact science. It is someone's best educated guess.
In my estimation, the winter fund raiser was a success. According to the contractor's estimation, the house will be finished by next week.
Relative dating allows you to compare the age of a substance with the age of another substance, but it won't actually give you the exact age.

The difference between a measurement and an estimation is that a measurement is an exact data while an estimation is a guess as to what something may measure. For example, you can use a ruler to get the exact measurements of a piece of paper. However, if you don't have a ruler, you can make an educated guess as to what the paper's length and width measurements may be.
No, not generally. Sometimes you may by chance (to a degree) find the exact number. Estimations are put in place to give us a rough guide to for instance experimental data.
there might be too many in the world to have an exact answer, but there could be an estimation.
Estimation is making a rough guess to the approximate answer but it does'nt have to be exact. Guessing is giving random answers without thinking whether it's approximate or not.
