No, the Intercity-Express (ICE) trains are not included in the "9-Euro Ticket" (or its spiritual successor, the "Deutschlandticket" / 49-Euro ticket). These flat-rate monthly tickets are designed strictly for "Local Public Transport" (ÖPNV) and "Regional Transport" (SPNV). This means you can use your ticket on all city buses, trams, U-Bahn (subways), S-Bahn (suburban trains), and Regional-Express (RE) or Regionalbahn (RB) trains throughout Germany. However, the high-speed, long-distance "White Trains"—which include the ICE, IC (Intercity), and EC (Eurocity)—require a separate, full-priced ticket. These premium trains are operated by DB Fernverkehr and are not part of the subsidized regional transport network. If you are caught on an ICE with only a 9-euro or 49-euro ticket, you will be considered to be traveling without a valid ticket and will face a "60-euro increased fare" fine. For travelers looking to go from Berlin to Munich using only the subsidized ticket, it is possible, but you must take a series of slower regional trains, which might take 10 hours instead of the 4 hours an ICE would take.
