Can I sponsor my parents for a green card when if I'm a full time college student?

You appear to be eligible to sponsor your parents assuming that they have no inadmissibility issues such as crimes, fraud, etc. On the question of financial sponsorship for your parents, there is a possibility that they may be able to financially support themselves on your I-864 affidavit of support under two scenarios and one in which they can sponsor themselves: 1.) The law appears to allow nonresidents who have income from a legal source to use that income on the petitioner's I-864 as long as there is the expectation that that income will continue after obtaining permanent residence – here, the TPS status with attendant work authorization would perhaps satisfy this scenario. 2.) The assets of persons without status can be put down on your I-864 to bolster the amount of income/assets that you have in support of the I-864. 3.) Persons without status who have earned income on a certain level for 10 years in the US can sponsor themselves through the new 10/24/24 form I-485 (page 8 part 3) which will become mandatory on February 10, 2025. The old I-864W which used to self-sponsor is being discontinued. Kindly note that as you are sponsoring each parent under the immediate relative category, each parent must qualify separately under his and her own set of circumstances under any of these scenarios.
