The Acceleration I agree should be lower, mainly due to the way he learned to start sprints was at that lowered crouch stance, with those angled platforms to push his feet off and the use of his upper body/arms to launch off the ground, it is completely different than what footballers do in body mechanics. Unless of course he is showing Messi-like bursts in the Australian League just from standing still.
The fastest in the world, yeah his TS was probably more than 99 when he was in training as a sprinter and competitive for that. Now, since he retired in 2017, it could be lower than 99 - I don't know I have not watched him play - but keeping an attribute at a high level even for a genetically gifted guy like him takes constant maintenance. If he is training as a footballer now, I imagine they would be working on his ball control and tactical things which would be non-existant, not that they would tell him to focus on just keeping his speed and be unable to coordinate with a team move and unable to control the ball.
Really and his speed might take a hit simply since he is running with cleats on a grassy surface, not a smooth track surface.
Agility 87? Does he show that?
The Attack/Def, DA, TECH, passing are poor compared to say a professional from EPL even Russian League, but these are all still professionals. In MLS even with out the speed, this set would be on the poor end of players playing in that league and actually looks like a solid USL player (lower league still professional), I imagine some League One players in England might have technical stats like that. I'm not saying its not possible he is that "good", just that there are professionals who have worked years for a living and they sit at that level - Usain Bolt just might be gifted in multiple areas and actually practised footballing skills whilst he was a sprinter and played matches on the side and is actually at that level.
How many competitive matches has he played for his club? I can't find any stats on trasfermarkt or football lineups.
