Yes, it's possible to need struts at this mileage. Also factor in the year of the vehicle 2002. 7 years of supporting the vehicle will cause an issue or 2. Here are some ways to check if your struts are bad.
1. Excessive bounce going over bumps or riding down the road. Harsh ride.
2. Bad road steering.
3. Tires have uneven tread( Looks and feels choppy)
4. Fluid coming out of strut.(Leaking)
5. Vehicle looks uneven.(Sagging)
6. Bottoming out over bumps.
When the mechanic stated that you needed shocks he/she should have stated the reason why. If you have none of these issues your shocks are more than good enough for you to drive safely for many more miles. Just keep in mind of the issues stated above.
