Since today there are mechanics such as the dummies (which gives 10%+ skill over time) and double skill events, it gets kinda hard to calculate the exactly amount of time.
So, in order to give an exact answer, I'm assuming you won't use either the dummy or train during the double event.
According to Tibia Fandom, you'll need 208h training each skill to up from 10 to 100, so 624h in total (please note all this calculations are done using exercise weapons)
This is equivalent from up one skill from 10 to 111 + about 63% to 112.
If, by any chance, you do all this using exercise weapons in a premmium dummy, you'll get skill 113. If you use all exercise weapons during some double skill events (remind that this would need at least 9 or 10 events, training non-stop) you would get 119. And if using both premmium dummy + double skill event, you'd get skill 120.
Just for curiosity, the amount of exercise weapons needed is 81 (27 per weapon type or 81 total) and you'd spend 612kk or 58,32k TC (depending if you buy it in-game on NPC's or in store)
