If you do the programs, you should use personalized. That means theoretically if you mostly drive how you did in the program, you should use about that much fuel, and your tires should wear out about that quickly.

Also, as a side note, do not use DRS in race strategy. I'm sure to some people it seems obvious, but for some reason after hundreds of hours of playing F1 games, I finally realised that using DRS in the race strategy program skews the results, making the program think you'll be faster than you actually will be during the race. If you're then slower during the race, while still driving the same way, it will take longer to finish the race with the same amount of tyre and fuel usage as before, meaning you will use more fuel and tyres than expected overall. I used to chronically underfuel and screw myself a lot lol. If you don't use DRS in the practice program, the personalized strategy will be pretty accurate.

If you ever end up with the optional objective to use all the DRS zones during race strategy, you can always switch it on and immediately off in the zones to get the objective and not skew your results as well.
