sorry to bother you but what’s the max level in destiny 2 without buying the dlc??

Oh, no bother at all! Base game, the highest is 20, went up to 25 and 30 for Curse is Osiris and Warmind. Forsaken the highest is 50, but the thing to keep in mind is that your actual experience level doesn’t matter as much as your light/power level. 🙂 Experience level mostly unlocks what you have access to.
