"The Universe is infinite" means that it is ever-expanding. You could never reach the end of it, because it is empty space. For there to be life, there must be matter. There is finite matter. You could, in ideal conditions with proper equipment (which nobody on Earth has) travel to the end of matter. Beyond that would be more space.
Since there is finite matter, the chances of there being an exact replica of earth are very slim, but still possible.
I believe it was Nietzsche that put forth this fun, but mind-boggling idea: Time is infinite. It goes on forever into the past and forever into the future. It doesn't stop, even if the world stopped. Matter is not infinite. There is a large number of ways to arrange all the matter in the Universe, but it would still be some actual number. Since no matter is being created, the number of possible arrangements would be a given. Given infinite time to arrange the finite matter, every arrangement will be made, even the arrangement that is you asking the question at hand. And, given that the number of ways to arrange matter is finite, and there is infinite time, it stands to reason that everything has already been arranged in all its ways. You've already asked the question at some point in history. Furthermore, since time is infinite, you've already asked the question an infinite number of times.
There are numerous flaws in that idea, but sometimes I like to overlook them just so I can imagine that crazy world.
The answer to your question is no, there is not infinite possibilities of life. With finite matter comes finite possibilities.
And conditions need to be just right for life to form (according to scientists, the intelligent life you seek would require a lot of carbon; other intelligent species could, in theory, be had with silicon). The possibilities of any life are slim, but you and I prove that it happens. Perhaps there is another you asking this question. I have a friend that proposed the thought to me years ago. It's unlikely, but so is our own existence. I don't know as if there is one mirroring our own, moment by moment, but I wouldn't be shocked if there was another Earth-like world with human-like species that has a fuzzinutzz-like person running around.
