I know you are all excited, but please use the sentence discussions only for language-related questions and answers. Irrelevant posts clutter the discussion and prevent others from getting answers easily and also afterwards finding the relevant/necessary answers becomes very difficult.
Turkish verbs may have lots of different suffixes depending on the time, person, sometimes intention or the type of the sentence. Verb has a much more complicated role in the sentence then it has in european languages. thus it is a complicated issue not very suitable to be explained here. But in short the answer to your question is "no" simply it is not always -ar -er
It's an agglutinative language which means that the suffixes or prefixes on verbs indicate tense, who is doing the action, etc. You can also add in prefixes and suffixes to show what object the action is being done to.
In other words, you can build an entire sentence in agglutinative languages by adding in prefixes or suffixes that would normally take several words in English.
Another notable agglutinative language and the one with which I am familiar is KiSwahili.
Examples from English to the agglutinative language of KiSwahili: "I am going to the store" "ninaenda dukani"
Ni- means I Na-means present tense enda- verb root duka- store ni (suffix on noun)- means the locative and is the substitute for "to" in Kiswahili
I hope this gives you a better idea of how agglutinative languages like Turkish work and allows you to carry on with a better understanding. Starting agglutinative languages can be difficult at first but once you understand the grammar then the prefixes and suffixes become building blocks making it easier.
-er/-ar is only used for one tense (called Aorist). And it's not even just -ar/-er; within the same tense, you also sometimes get the -ır/-ir/-ur/-ür endings, depending on the verb.
But then there are other tenses too. I believe the number of the tenses in Turkish well exceeds 20. You will learn them all as you progress.
