If I keep betting the same number in a lottery, do I have more chances at winning than if I choose different numbers each time?

If the winning numbers are random, and my betting numbers are also random, then there are two random variables, meaning that there are fewer chances for me to win. 

However, if I keep betting the same number over an over, there is one fewer random variable in the equations, giving me more chances to win. Is this right?

Your odds will be the same if you pick the same number or random numbers, assuming a fair lottery. 

If the lottery is fair, it means that each winning set of numbers are drawn randomly and are not dependent on any previous set of winning numbers. 

Instead of worrying about the specifics of a lottery, consider a simple example of a dice roll. You can bet on any one of six numbers, so every time they roll the die you have a 1/6 chance of winning. That 1/6 chance is independent of whether or not you bet on "1" every time or if you a bet on a random number. A lottery is like a dice roll, only the die has like 100 sides and they roll it 5 times.
