Those actually all look significantly bad. The packet loss at hop 1 is unacceptable. Getting 10-25% packet loss is very challenging for any application to work well with - especially gaming.
Having packet loss at hop 1 has a couple of possible sources of problem. First, if you're using a wireless connection, try going hard-line instead of wireless. Packet loss is pretty common with wireless connections with interference or far enough between the wireless router and the computer/device.
If you have another computer or pingable device at your house, try pinging that device to see if you get 0 packet loss. Any local devices should show up with 0ms of latency and no packet loss. If you're seeing 20% packet loss internally, then you know it's something you need to solve yourself, not have your ISP solve.
To eliminate your own hardware as a source of problems, you'll need to plug a hard-line wire directly into your computer, and plug the other end into your provider's box in your house. Even that leaves your computer and the network cable as possible problems, so if you have another computer and another network cable, try using both of those. If you still get packet loss in all these situations, then you've (mostly) eliminated yourself as a source of the problem and you can start working with your ISP. Of course you *can* involve them before you've eliminated yourself as a problem, but it's hard to give them too hard of a time about fixing a problem if it might be in your house.
