If I have a raffle with 1453 tickets and someone buys three of those tickets what are the odds that that a person will win twice?

This is an ill-defined question. No one can win twice unless there are more than one winning ticket.
So what is the setup? How many winning numbers/tickets are there?

There are three prizes, first second and third. Three tickets will be drawn without returning any previously drawn tickets to the original “pot” of tickets.

.
There are \(\dbinom{1453}{3}=510,209,326\) ways to have three tickets.
There are \(\dbinom{3}{2}\dbinom{1450}{1}=4350\) ways to have three tickets such that two two of which are winners.
There is only one way to win all three.
