Why do athletes and others give thanks to God for their success? You've answered the question yourself!
<< There are poor children starving, people being being killed, and other horrible things happening all around us. >>
These people understand that fact that they have done nothing to deserve a good environment, good physical health and opportunities. They understand that they could have been born deformed, born into poverty or been put into any number of other situations that may have kept them back. In all probability, they have leaned on The Lord when they felt down or discouraged and He helped them to continue. For those of us that believe, we know that although we continually goof things up, God has an overall purpose or plan for us and we ENJOY being in His will and trying to please Him because we LOVE Him. If your parents helped you acheive something great, wouldn't you give them credit and want them to be able to be proud of you? It is the same with us and God our Father.
<< besides, like god cares who wins, because someone always loses >>
Well, yeah, He does! Do you have children? Do you love them? Do you care about what is important to them? Ultimatly, since God is omniscient, He would rather have a child lose than have that child become prideful, but rest assured whatever He does it is for the good of those who love Him.
<< Funny, that they made it to the Olympics themselves..not God. >>
Rather confused logic since these athletes believe that it was God who created all things, they rightly suppose that without a universe, there are no Olympics. Ultimately, it is God who have provided every good and perfect thing for us.
<< The argument is that athletes use God's name in vain, as if God guided them to victory by making them run faster or perform better in general. This is a very selfish proposition, that they are so special that God even takes time to make sure they win races, while people worldwide are dying - why doesn't God save them? >>
First, they are not taking the Lord's name in vain. The Bible is clear that we are to give thanks for all things, and they are doing so. Second, God came to Earth and died on the Cross as a payment for our sins so that people would not have to die an eternal death. The problem with your question is that it presupposes that this life is all there is. Consider, if eternal life and death are true, then the death He saves people from is MUCH more important than the death of this temporary shell called a body that we currently live in.
