Karl-Anthony Towns says he had a "5 percent chance of surviving" the scary car accident he was involved in last week ... and he's "blessed to be alive" and mostly uninjured.
The Minnesota Timberwolves star was heading to the Minneapolis airport for the team's trip to New York last Thursday ... when the car KAT was traveling in was hit by a semitruck traveling at 45 miles per hour.
Towns -- who missed the Wolves' past 2 games as a part of being in concussion protocol -- gave details on the accident at practice on Monday ... saying he knows it could have been MUCH worse.
"I'd say I had a 5 percent chance of making it out alive," KAT says, "I hit the 5 percent mark. I'd say 4 percent was to be seriously injured and 1 percent was to be minorly injured ... and I came out in the 1 percent."
