no. because the things you mentioned in the title are not randomized.The only randomized items that you could purchase in the market were the falcon,dragon etc mod packs and they dont exist in the game anymore. If you spend 20 plat on an item you get exactly what you spent that 20 plat on. All purchases are direct purchases now. Buying boosters gives you exactly what you pay for, a doubling of the drop chance or doubling of the value you get in the drop. Lootboxes are pay-per-roll which would apply to the old modpacks as you couldn't control what you get.
